Annual Work Summary of the Metrologist in the Production Planning DepartmentDear leaders, hello. I am Wang Yi, a metrologist in the Production Planning Department. I was transferred to the Production Planning Department on July 20, 2017. After being transferred to the Production Planning Department, I made an effort to adapt to the role of a measurer as quickly as possible and complete my tasks. During these little over half a year of working, I have recognized many of my shortcomings; especially at the beginning, I relied on Engineer Zhang for everything. After a few months of learning, I gradually adapted to this job and learned how to carry it out properly. The following is my annual work summary for 2017: (I) Weighing equipment 1. Calibration status of weighing scales Weighing scales are devices that require mandatory calibration, with a calibration cycle of 6 months. The last calibration period for these scales was from May 3, 2017, to November 2, 2017. We have already contacted the calibration agency to complete the calibration of the scale as soon as possible. 2. The operation status of the truck scale is as follows. Below are the problems that occur during its operation, their causes, and measures to resolve them: Problem: When logging into the truck scale system, it shows that COM initialization has failed; no serial port can be detected by the computer. Although there are values displayed on the weighing indicator, no values appear in the truck scale system. Reason: The static electricity from the computer’s main unit cannot be discharged due to excessive resistance. Measures: Turn off the weight display, computer host, and printer in sequence. Unplug the power cord of the computer host. Continuously press the power button on the host 10–20 times to discharge static electricity. Redo the wiring by connecting the main cable of the power strip to the wall outlet, and connecting the power cords of the weight display, the main unit, and the printer to the power strip. Question: The weighing scales are divided into the east scale – used for weighing raw materials upon arrival at the factory, and the west scale – used for weighing products before they leave the factory. When products are shipped from the western weighbridge, the shipper and recipient details on the weight ticket are reversed. Reason: An error occurred in a file within the scale system. Action: Contact the scale’s after-sales service to replace the documents. (Note: The files for the east and west scales have been copied to prevent further issues with the scale system’s files.) Problem: It is not possible to log in to the scale system. Reason: The company’s server system has crashed, preventing access to Kingdee; the scale system is integrated with Kingdee. Action: Contact Finance Director Zhang Zhiqiang to resolve the server issue. Problem: The truck scale slip cannot be printed. Reason: Printer malfunction. Steps: Redownload the driver, reconnect the printer cable, restart the printer, and reconfigure the printer on the computer. Question: The weight display and the data on the computer show half the weight. Reason: When the weighbridge was restarted, a vehicle remained on it. Measures: The driver must drive the vehicle off the scale, then restart the scale. Only after 30 minutes of the scale being restarted can the vehicle be driven onto it again. 3. Maintenance of weigh scales: Standards for the inspection and maintenance of weigh scales have been established, as follows: For the electronic weigh scale’s structure: (1) Check the gaps around the scale platform; this inspection should be carried out on a weekly basis. (2) The cleanliness of the scale platform should be checked at the end of each shift. (3) Maintenance of the scale body connector and hygiene of the support head; inspection frequency is once per quarter. (4) Welding operations are strictly prohibited on the scale; inspections shall be carried out at the end of each shift. (5) Inspection and adjustment of the limit clearance, with an inspection cycle of once per quarter. (6) Cleaning of water accumulation in the weighing machine foundation pit; inspection frequency is once per shift. (7) Maximum total weight limit for vehicles on the scale; inspection frequency is once per shift. (8) Vehicles or goods must not be left on the scale platform for extended periods; the inspection cycle is once per shift. Electronic scale display section: (1) The cleanliness of the weighing display unit, printer, and computer; inspection is to be carried out at the end of each shift. (2) Check whether the system grounding wire is secure on a weekly basis. (3) Hygiene inspection of junction boxes; the inspection cycle is monthly. (4) The scale should be zeroed out promptly when it is empty, with inspections carried out at the end of each shift. (5) Electronic weighbridges shall be regularly calibrated, with a inspection cycle of six months. (6) When the truck scale is not in use, the power supply should be cut off; the inspection cycle is daily. Regular inspection items for electronic weigh scales: (1) Visual inspection of the weighing platform, with an inspection frequency of once per day. (2) Adjustment of the scale body limits; the inspection cycle is once per quarter. (3) Inspection of the unloading bolt clearance, with an inspection cycle of once per quarter. (4) Inspection of the positions of scale body connectors; the inspection cycle is quarterly. (5) Inspection of the junction box sealing and connections, with an inspection frequency of once a year. (6) Inspection of instruments and instrument errors, etc., is carried out on a quarterly basis. 4. Weighbridge maintenance records: The weighbridge operator carries out daily maintenance tasks on the weighbridge. If any problems arise, the operator first tries to identify and resolve them on his own. If the weigher cannot resolve the issue, he/she should inform the meter reader, who will then go to the scale to fix the problem. Once the issue is resolved, the weigher shall make a record in the shift handover book. In the role of a meter reader, I carry out systematic and thorough maintenance of the weighing scales on a monthly basis, adhering strictly to the established standards for such maintenance, and keep records of it all. This ensures that the weighing scales function properly and maintain their proper service life. (II) Measuring instruments 1. Inspection status of measuring instruments (1) The number of pressure gauges that were last inspected was 174, with the inspection period ranging from May 16, 2017, to November 15, 2017. (The calibration date has passed.) On December 14, 2017, 138 pressure gauges (64 manufactured and 74 used for storage and transportation) were sent to the Dongying Metrology, Testing and Calibration Institute; the calibration of these pressure gauges was completed approximately 30 days later. (2) The number of transmitters to be calibrated is 5, with the calibration period running from June 29, 2017, to June 28, 2018. (Currently within the calibration range.) (3) The number of gas detectors to be calibrated is 121; all gas detectors in the plant are to be calibrated, with the calibration period from June 7, 2017, to June 6, 2018. (Currently within the calibration range.) (4) Types and quantities of instruments to be calibrated in the laboratory: 1 pipette of 1 ml capacity, and 1 pipette of 10 ml capacity ； There is 1 volumetric flask each of the following sizes: 25 ml, 50 ml, 100 ml, and 500 ml ； There is 1 measuring cylinder of 500ml size and 1 of 1000ml size ； 2 burettes with a capacity of 25 ml each ； The verification cycle for measuring instruments verified by the laboratory is from June 12, 2017, to June 11, 2020. (Currently, they are within the verification period.) 2. During the company’s trial production phase, when a pressure gauge was damaged, an appropriate replacement pressure gauge was selected ； The Production Planning Department, the Production Operations Department, and the Storage and Transportation Department jointly completed the calibration of the flow meter for C4 raw material entering the plant ； If measuring instruments such as thermometers and flow meters fail, the dispatch team should be notified immediately; the dispatch team will then contact the instrument maintenance team to carry out repairs, ensuring the normal trial production of the equipment ； Measuring instruments in the laboratory, such as pipettes and volumetric flasks, are accurate, ensuring reliable results for pilot production testing and analysis ； After the calibration of the gas alarm is completed, it should be used normally to ensure safe trial production of the device. (III) The company’s administrative department has contacted the certification body to pursue certification for the three-standard system, with the support of the Production Planning Department, which provides the materials required by the certification body (the records related to pressure gauges, gas detectors, the laboratory, and transmitters have been submitted to the Administrative Office of the Comprehensive Management Department). The Production Planning Department assists the Comprehensive Management Department in completing the certification of the company’s three-standard system as soon as possible. 2018 Work Plan (I) Weighbridge Equipment 1. Calibration status of the weighbridge: The last calibration period for this weighbridge was from May 3, 2017, to November 2, 2017; thus, its calibration has expired. We have already contacted the calibration agency to complete the calibration as soon as possible. The calibration cycle for weigh scales is half a year; when it’s time to calibrate the scale again, contact the calibration agency one month in advance, prepare the materials required by the agency, and complete the calibration ahead of time. 2. Operation of the scale: After more than half a year of work, I have acquired a lot of knowledge on dealing with issues related to scales. When problems arise with the scale, I address them right away; at the same time, I continue to deepen my understanding of scale-related matters in order to be able to resolve such problems independently. 3. Maintenance of the scale: In the new year, it is necessary to strictly adhere to the standards for maintaining the scale. The scale should be systematically and thoroughly maintained on a monthly basis, with proper records kept of such maintenance activities. By carrying out proper maintenance of the scale, its normal operation can be ensured. It is also ensured that the weighing operator performs maintenance on the scale every day, including cleaning the scale surface and removing waste from beneath it, so as to ensure the accuracy of the scale and enable it to carry out weighing tasks effectively. (II) Measuring instruments
1. Calibration status of measuring instruments
A total of 138 pressure gauges (64 produced and 74 stored/transported) have been sent to the Dongying Metrology and Testing Institute. On January 20, we contacted the institute to inquire whether all pressure gauges had been calibrated. Once it is confirmed that all pressure gauges have been calibrated, we will prepare the necessary documents and go to the Dongying Metrology and Testing Institute to retrieve them. The meter reader keeps a record of the pressure gauges that have passed the calibration and replaces them on-site. For pressure gauges that fail the calibration, first analyze the reasons to determine whether the problem lies with the gauge itself or with the calibration facility ； If the pressure gauge analysis shows no issues, conduct a recheck ； If there is a problem with the pressure gauge, the department using it shall submit a purchase plan to acquire a new pressure gauge. It is important to distinguish between pressure gauges of types A, B, and C; by continuing to learn more about pressure gauges, one can be qualified for the role of a meter reader. The thermometers and transmitters were calibrated. Upon inquiring with surrounding companies, we received feedback that the specific calibration intervals for thermometers and transmitters are determined based on factors such as the process environment of the particular application, as well as product quality and lifespan. Information found online indicates that calibration should be performed once every two years. The metrologist conducts selective calibration based on the company’s specific application scenarios. Subsequently, in coordination with the Safety, Health, and Environment Department and the Operations & Maintenance Center, the calibration of thermometers and transmitters is completed. The calibration period for gas detectors is from June 7, 2017, to June 6, 2018. Gas detectors are classified as devices that require mandatory calibration, and all of them must be calibrated. It is necessary to contact the calibration agency one month in advance, prepare the documents required by the agency, and complete the calibration of the gas detectors ahead of time. The calibration period for the measuring instruments in the laboratory is from 01/07/2017 to 06/11/2020; the usage of these instruments is checked every quarter, with relevant records kept. The meter reader requests the laboratory records from the Quality Control Department on a monthly basis, and checks the measuring instruments based on those records. 2. Operation status of measuring instruments: In 2018, the inventory records of all measuring instruments in the plant were updated. The Production Planning Department works in conjunction with the warehouse for \"coordinated management.\" When a measuring instrument gets damaged, the department that uses it goes to the warehouse to obtain a replacement; the warehouse must inform the Production Planning Department, and then a metering technician goes to the warehouse to record the information regarding the replacement, ensuring that the inventory records of all measuring instruments in the factory are always up to date. (III) The metrologist in the Production Planning Department of the three-standard system shall continue to cooperate with the Comprehensive Management Department by providing the information required by it, in order to complete the certification of the company’s three-standard system as soon as possible. After the company completed the certification for its three-standard system, it implemented this system across various departments to further improve the relevant regulations. (IV) The Production Planning Department of the 6S system implements the company’s regulations by carrying out 6S management system plans within this department, thereby improving the company’s systems. 2018 is a brand new year, as well as a year for self-challenge! I will carefully reflect on my experiences, address the shortcomings in my work over the past year, and strive to do better in my duties. I aim to become a qualified professional in measurement management and calibration, so as to contribute to the development of Dechen. I sincerely wish that the Dechen family will continue to thrive and get better. I hope Decent will achieve even greater success in the new year. Surveyor: Wang Yi, December 25, 2017
