For new projects that require measuring instruments, the Engineering Management Department will allocate such instruments based on the company’s inventory of measuring equipment. If it is necessary to purchase new measuring instruments, a \"Instrument Purchase Request Form\" must be filled out, and the purchase can only take place after approval by the company’s senior management. For the transfer of project measurement instruments, the unit receiving the instruments and the unit transferring them must fill out an \"Instrument and Equipment Transfer Form\", indicating the condition of the instruments as well as any accompanying accessories. III. Use and Management of Instruments and Equipment (I) Unpacking, Packing, and Placement of Instruments 1. Before unpacking an instrument, the instrument box should be placed flat on the ground; it is strictly prohibited to unpack the instrument by holding it in the hands or carrying it, to prevent the instrument from being damaged if it falls to the ground during unpacking. After opening the box, make sure to check how the instrument is placed inside, so as not to put it back in the box in its original position after use. 2. Before removing the instrument from the box, loosen all the locking screws. When taking out the instrument, use one hand to support its base while holding the bracket with the other hand, and remove it gently; it is strictly prohibited to lift the instrument by the telescope or the horizontal axis. After removing the instruments and components used, the box lid should be closed promptly to prevent dust from entering the box. The instrument box is placed near the station; no one is allowed to sit on it. 3. When setting up the instruments, choose a location with a flat terrain and minimal construction interference, based on the position of the control points. Be sure to pay close attention to the instruments; check whether the instrument tripods are secure, and only release them after confirming that the screw connections are firm. However, it should be noted that the tightness of the connecting screw should be appropriate, neither too loose nor too tight. 4. After the observation is complete, the foot screw as well as the braking and fine-tuning screws should be returned to their normal positions, and dust on the upper surface of the instrument should be removed using lens cleaning paper or a soft brush. Then remove the instrument, hold it with both hands, and place it back in its original box in the same position as when it was taken out. Before closing the box, gently tighten each braking screw. Once it has been confirmed that all accessories are present, the box lid can be closed gently; it should be sealed properly before the lid is fully closed. Do not apply excessive force to avoid damaging the instrument. (II) Use and Management of Instruments 1. All types of measuring instruments shall comply with the regulations set forth by the Bureau Group Company regarding the management of measuring devices. 2. Newly purchased instruments and tools should be calibrated at a **legal metrological testing institution before use. For newly purchased instruments or those transferred to other projects, it is necessary to read the instruction manuals carefully. Starting from the basic operations and progressing to more advanced ones, one should practice repeatedly, summarize, and strive to become proficient in using the instruments so as to maximize their functionality. Those who are not familiar with the operation of these instruments should not use them blindly. 3. All types of measuring instruments must be regularly inspected and calibrated before and after use; proper maintenance should be carried out during use, and timely care should be given after use. 4. All types of optoelectronic and laser instruments must be regularly sent to qualified departments for inspection. The identification time should not exceed the specified time to ensure the accuracy and precision of the measurements. 5. It is strictly prohibited to use instruments that have not been tested and calibrated to their factory accuracy, that are past their calibration deadline, or those with defective parts or unclear readings. 6. When using a total station or a photometric rangefinder, it is prohibited to direct the telescope at the sun without a filter, in order to avoid damaging the eyes and the light-emitting diodes in the ranging unit. 7. When working in strong sunlight, during rain, or in humid conditions, it is essential to work under the protection of an umbrella. 8. Handle the instrument with care to avoid severe impacts and vibrations. Before setting it up, check the stability of the tripod. The staff must not leave the instrument throughout the operation to prevent accidents. 9. When changing stations, the instrument should be taken out of its case and packed, even if the distance is short. After the measurement work is completed, turn off the device, remove the battery, and pack it up. For long-distance transportation, appropriate shock absorption measures should be employed to prevent the instrument from suffering sudden vibrations. 10. Measurement instruments should be stored in a dedicated warehouse, with an environment that is dry, well-ventilated, and protected from shocks, fog, dust, and rust. The instrument should be kept dry; after being exposed to rain, it should be wiped dry and placed in a well-ventilated area to dry before being put back into its box. All instruments must not be exposed to pressure, freezing, moisture, or high temperatures; the instrument box should not be placed near stoves or heating pipes. 11. When transporting the instrument over long distances, proper measures must be taken to protect it from shocks and moisture. When loading, be sure to keep the instrument upright; it must not be inverted. When the measurer is traveling by car with the instruments, they should place the instruments on shock-absorbing pads or hold them on their legs to prevent damage from vibrations and bumps. 12. It is necessary to establish and improve systems such as registers for measuring instruments and equipment, cards for precision measuring instruments, and instrument archives. For the issuance, receipt, or relocation of instruments, registration and approval procedures must be followed. 13. Regarding the management of measuring instruments, the company’s precision measurement team formulates inspection and evaluation methods; units and individuals that excel in maintaining these instruments are rewarded. Those responsible for damaging the instruments due to improper use or poor storage shall be held accountable, and penalties shall be imposed as appropriate. 14. Measuring instruments and tools are considered unqualified if they are in the following conditions: damaged ； Overload or misoperation ； The functionality has shown suspicious behavior ； Display is abnormal ； The specified weekly inspection verification interval has been exceeded ； The integrity of the instrument seal has been compromised ； When optoelectronic and laser instruments have exceeded their service life, suffer from severe zero drift, produce unstable measurement results, and have low reliability of those results, it is necessary to apply for their disposal ； When conventional instruments cannot be repaired after damage, or when they are worn out, their readings are difficult to discern and their performance is unstable, affecting the quality of measurements, it is necessary to apply for their disposal. 15. Requests for the purchase of measuring instruments as well as their disposal are submitted by the project department to the company’s engineering management department, where they are approved by the company’s chief engineer and relevant supervisors. The company’s precision measurement team checks the instrument allocation and management across all projects every six months, ensuring that the records, actual items, and cards are in agreement and that all technical documentation is complete. 16. Measuring instruments must be kept under the responsibility of a designated person. For valuable and precise measuring instruments (such as total stations, precision levels, and laser plumb bobs), it is necessary to assign a specific person to take care of them, to use them only by that person, and to send them for inspection by that same person; others are not allowed to use them casually in order to prevent damage and loss of accuracy. (II) Incentives and Penalties for Instrument Management 1. In order to strengthen engineering survey management, promote scientific management of such activities within our company, prevent survey-related accidents, meet the needs of economic development, and fully leverage the enthusiasm and creativity of survey staff, necessary spiritual and material rewards will be given to those units and relevant leaders who excel in engineering survey management after a project is completed. Those who are diligent and thorough in their measurement work, study diligently, are proficient in their tasks, improve their skills, and achieve outstanding results can be recommended for promotion. 2. Those who, in their production and business activities, violate measurement and metrology regulations, engage in fraud, fail to enforce measurement and metrology management systems properly, and cause losses to projects due to errors in measurement work, should be subject to appropriate penalties. Those who conceal measurement accidents from reporting must be held accountable, along with the supervisors and relevant personnel. 3. Failure to manage measuring instruments properly and inadequate storage, which leads to damage and affects their normal use; the responsible persons will be punished depending on the severity of the situation. 4. The project’s engineering department shall establish appropriate management procedures for measuring instruments based on the actual conditions of this project, to ensure that such instruments are in good condition and accurate. In summary, in order to strengthen the management of measuring instruments, standardize the relevant management systems, ensure that these instruments are used correctly and with accuracy that meets the requirements of relevant standards, so as to obtain accurate and reliable measurement data that can better serve our engineering projects and guarantee effective control in engineering surveys, it is hoped that everyone will comply voluntarily.

Instrument and Meter Management System (I) Concept of Instrument and Meter Management 1. Definition of instruments and meters. Instruments and meters used in industrial enterprises refer to devices used for characterizing the surface condition, technical properties, and other characteristics of products, as well as for measuring, calculating, controlling, testing, and indicating the status of the production process; among these, those that are used solely for indication are called meters. In a broad sense, instruments are tools that enable humans to observe, detect, regulate, and control the physical movements of the objective world. 2. The tasks of instrument management at the team level in enterprises. The management of instruments and meters in work teams refers to the overall set of tasks involving the requisitioning of instruments and meters needed for production, their proper use, careful maintenance to maintain their performance and accuracy, as well as compliance with various management regulations. The tasks related to the management of instruments and meters in work teams are as follows: First, implement the systems for the management of instruments and meters ； Second, use instruments and meters properly to ensure their proper operation as well as the reliability and accuracy of the data obtained ； Third, carry out proper maintenance, storage, inspection, appraisal, disposal, accounting, record-keeping, and statistics ； Fourth, keep the technical documents (including certificates of conformity) properly ； Fifth, handle instrument and gauge accidents properly. (II) Specific tasks for the management of instruments and meters in enterprise work teams 1. Issuance of instruments and meters and establishment of records. The team formulates process plans for new products and renovation plans for equipment and instruments in accordance with the provisions of the production process documents, identifying items that are still incomplete or need to be added. Then, the workshop technician submits the request to the competent authority for approval or to obtain a plan for acquiring the instruments. Upon arrival, go through the pickup procedures, establish an account card, and inspect the instruments. The team’s inspection of instruments is usually carried out in conjunction with the instrument operator, and it includes an external inspection, that is, checking whether the outer packaging is damaged ； A comprehensive inspection involves checking the main unit, auxiliary equipment, accessories, special tools, accompanying drawings, technical documents, instructions, as well as peripheral device connections, all in accordance with the packing list and instructions ； Performance testing involves checking each item in accordance with the technical specifications specified in the manual. For large, precision, and rare instruments, an acceptance report must also be filled out, and the drawings and technical documents should be submitted to the higher-level authorities for archiving; the work team generally only keeps the instruction manual (or a copy of it). 2. Use instruments correctly. First, pay attention to the operating environment and conditions of the instruments. General instruments and meters have specified operating conditions, such as operating ambient temperature and humidity, which must be strictly followed. Check the certificate of conformity before use; instruments without such a certificate should not be put into operation. Under normal conditions, the area where the instrument is operated should be well-ventilated, free from strong magnetic fields, corrosive substances, and severe vibrations; attention should also be paid to dust prevention. Second, use instruments within the scale permitted by technical specifications. There is no universal instrument in the world; all instruments are designed to perform functions of observation, detection, adjustment, and control within a specific limited area. Therefore, they must be used within their designated scope. It is necessary to ensure that all instruments and equipment operate properly, without using inferior substitutes for high-quality ones, and without exceeding their capacity limits. Ordinary instruments are all adjusted and calibrated, and some of their components are sealed; it is not allowed to disassemble or take apart these instruments without permission. When in use, appropriate force should be applied to the operating and control handles, shapes, and buttons. Third, pay attention to the operating procedures for the instruments. Before use, check whether the power supply and other power sources are compatible, have proper contact and sealing, and whether all peripheral accessories are properly configured; only after everything is ready can the device be turned on. All radio instruments have a preheating and stabilization process, which should be taken into account when using them. Other operating sequences, methods, continuous usage time, accuracy of use, limits of use, etc., shall be carried out in accordance with the regulations. 3. Comply with the periodic inspection system. To ensure the accuracy, consistency, and reliability of the functions of instruments and meters, the team must, in accordance with the regulations set forth by the relevant supervisory authorities regarding periodic calibration, submit these instruments and meters for inspection and calibration on time and in sufficient quantities. They must also handle the transfer of measuring instruments properly, and keep proper records of the calibration cards or forms. 4. Ensure proper maintenance of instruments and equipment. The main aspects of maintenance for instruments and equipment include dust prevention, moisture protection, corrosion prevention, and anti-aging measures. Wipe the casing with a dry cloth daily, and cover it with a cloth when not in use. Some instruments also require protection from light, and the dust accumulated on these instruments should be removed regularly by qualified personnel. 5. Ensure proper management of precision instruments and equipment. Precision, valuable, and rare instruments and equipment require thorough attention in terms of usage, storage, maintenance, and inspection. For such equipment, a management and maintenance system of “four fixations” and “five no’s” must be strictly implemented. First, the “four fixations” refer to: fixing the location of use, fixing the personnel responsible for use, fixing the personnel in charge of maintenance, and fixing the specialized management system. Second, the “five no’s” refer to: never leaving the device unattended while it is running, not using precision instruments in a careless manner, not operating them when they are faulty, not violating the operating procedures, and not stacking other instruments or items on top of the device. 6. Carry out other management tasks. First, ensure proper management of instrument accessories. The loss of accessories is a common occurrence during the use of instruments, and such losses or damages often prevent precision and expensive instruments from being used further, severely impacting production or research activities. Therefore, management must be effectively strengthened. The management method involves creating accounts for the accessories along with the instruments, designating fixed storage locations, establishing a borrowing system, and specifying the procedures for handing over instruments and accessories when they are used by different people. Second, ensure proper storage of instrument technical documentation. The instrument manuals, operating procedures, and other technical documents kept by the team should be stored together with the team’s process documents; when there is a change in team leader, these documents must be sorted out and handed over. These materials can only be borrowed and cannot be kept privately. Third, the handling of lost instruments and meters. In the case of instruments kept by individuals, any loss, whether due to subjective or objective reasons, must be dealt with seriously, and the matter must be reported immediately to the relevant authorities. Depending on the circumstances, administrative sanctions along with financial compensation should be imposed. All units should establish a compensation system for lost instruments. Fourth, the handling of instrument accidents shall follow the methods for dealing with equipment accidents. Fifth, the scrapping and utilization of instruments and meters. If instruments and equipment cannot be repaired due to long years of use, poor performance, severe damage caused by accidents, etc., or have lost their value as a result of technological advancements, the team can submit an application for disposal to the relevant authorities through the workshop. After technical evaluation and approval by the relevant authorities, the responsible department fills out a scrap application form, submits it to management for approval, and the item is then officially scrapped. Instruments that have been scrapped are handled uniformly by the competent authorities.

Shift handover system: This system is established in accordance with the company’s principles regarding labor organization and discipline, in order to regulate the behavior of electrical and instrumentation personnel and to facilitate more effective maintenance of such equipment. 1. The shift supervisor on duty that day is responsible for coordinating the assignments of the electrical and instrumentation team members throughout the day; all members must unconditionally comply with these arrangements. If there are other tasks to be carried out, they must inform the shift supervisor on duty in advance. 2. During the morning roll call, employees must gather at the basketball court and line up to proceed to the production area for shift handover. Except for those on leave, on vacation, on scheduled rest days, or engaged in maintenance tasks, those who fail to show up will be considered late; those carrying out tasks must explain the situation to the attendance officer. 3. During the shift handover, the departing shift leader first informs about any equipment issues that occurred during the shift and how they were resolved, as well as information regarding tools, cleanliness, and unfinished tasks. Then, the incoming shift leader assigns personnel and outlines the tasks to be carried out. 4. Shift handovers must be carried out seriously and thoroughly, with strict adherence to the “six handovers” and “six non-acceptances”. “Six Reports”: Completion status of tasks (including monthly plans, weekly plans, and completion of calls related to the position) ； Status of outstanding issues ； Implementation status of process technical specifications ； Handover of area hygiene and preparation for the next production shift ； The quantity and condition of spare parts, tools, equipment, and other materials on hand ； Submit the superior’s resolution and report on the implementation status. “\"Six no-acceptances\": Do not accept if the above six aspects are not clearly explained ； Records that are incomplete, inaccurate, or insufficient will not be accepted ； No connection if the equipment is not properly maintained or accidents are not handled properly ； I will not take on issues whose handling has not been clearly transferred ； If the process parameters are not met due to human error, acceptance will be denied ； Power disconnection and restoration procedures must be completed properly before any such action can be carried out (these procedures are applicable to electricians). Those who violate the above-handover regulations will have 5 points deducted from their score per incident; in cases of serious violations or incidents such as equipment damage, fines or suspension of work/overtime will be imposed. 5. A sign-in system is in place for leaving work at noon and starting work in the afternoon: 1) During winter, the working hours are 11:45 and 13:20; sign-ins are collected at 12:05 and 13:30. No late sign-ins or sign-ins on behalf of others are allowed, and those who do not sign or have their signatures done will be treated as being early or late. 2) During the summer schedule, at 11:45 and 13:55, the attendance officer brings out the attendance sheets; they are collected again at 12:05 and 14:05. No supplementary signatures or proxy signatures are allowed, and those who do not sign or have their signatures done in their place are treated as being early or late. (The attendance clerk is responsible for bringing out and collecting the sign-in books at the designated times.) 6. Roll calls are held at 17:00 in winter and 17:20 in summer; except for those on leave, on permission, or engaged in maintenance tasks, anyone who fails to show up will be considered to have left early. Those carrying out tasks must explain the situation to the attendance clerk. 7. During the roll calls at the start and end of work, before and after class, the shift leader summarizes the work completed and the tasks accomplished on the previous day (the current day). 8. Late arrivals and early departures will be handled in accordance with the assessment system and the company’s relevant management regulations. If there are three instances of being late or leaving early in a row, or five such instances in total within a month, the matter will be referred to the HR department for handling. 9. Sign-in and roll-call take place in the control room; everyone must line up neatly. First, the shift supervisor on duty that day handles the relevant tasks, followed by the attendance officer conducting the roll-call, and then the start-of-shift and end-of-shift meetings are held. 10. The work attendance system must be strictly enforced, and the attendance clerks must carry out their duties diligently and rigorously. 11. This system shall come into effect as of today.

Instrument automation design management 1: In principle, the design of instrument automation projects that require significant investment and involve complex technical aspects during renovation and upgrading should be carried out by the design department; secondary units are not allowed to carry out such design work on their own. 2 For the instrument automation upgrade projects identified by the company, the relevant departments provide detailed technical specifications; after thorough evaluation and technical approval by the company’s Operations Department, design work is commissioned. .3 The designer shall carry out the design in accordance with the requirements of the design commission and **relevant design standards and specifications. Prior to the design, a \"Feasibility Analysis Report\" should be prepared as necessary; after comparing various technical and economic options, the option that is both technologically advanced and economically reasonable should be selected. A preliminary design is prepared for review, combined with a cost estimate for submission for approval; once it is reviewed and approved by the company’s logistics department, the construction drawings are designed. 4 After the construction drawing design is completed, it undergoes review and any necessary modifications are made; thereafter, the drawings are stored in the database and distributed. 5 Designers should have a forward-thinking approach to technology, possess extensive knowledge of technical information, and employ advanced instrumentation and automation techniques.
