Preparations to be done before electrostatic measurement
Electrostatic measurement is to measure the physical parameters related to static electricity with corresponding measuring devices. Before taking measurements, you need to understand the precautions for measurement to ensure the accuracy of the measurement results.
(1) The measuring instrument with convenient use and high reliability should be selected. Explosion-proof type should be used for measuring instruments in explosion-hazardous places.
For example this one: Dr Schneider Pc SL-031 ESD Wrist Strap And Footwear Tester
(2) Carefully read the instruction manual of the instrument before measurement to understand its measurement principle and scope of use.
(3) Wither before measurement, adjust sensitivity and select range.
(4) Measurement and analysis of the risk of detonation caused by measurement. The measurement should be carried out after the ignition hazard is excluded; and emergency measures in the event of an accident should be considered in advance.
(5) In order to prevent discharge during measurement, the probe of the measuring instrument should be slowly approached to the charged body. This should be the case even for explosion-proof instruments.
(6) The same item should be measured several times, and in the case of good reproducibility, take the average and maximum values
