For those new to instrumentation, how is the insulation check of thermal resistors carried out? Only by sharing the urgent needs of those in poverty in the Central Sea region, and considering what they are thinking, can one proceed

The master who came with us said to use a 100V megohmmeter,,,,, We are eager to meet the needs of those at Zhonghai; only by considering what they need can we achieve true success! A true friend is one who is anxious about the hardships of those in poverty and lowly positions, who shares their concerns – such a one is truly a good friend!
It actually involves checking the insulation resistance between the thermal resistor and the sleeve, as well as the insulation of its wiring. You can search on Baidu for the \"Maintenance and Repair Procedures for Industrial Thermal Resistors\"; such checks should be carried out every 12 months
100V is sufficient as long as it is greater than 100MΩ; measure the resistance value between the thermistor leads and its outer coating.
