Points to pay attention to when measuring an electrostatic tester

Electrostatic tester is a non-contact portable electrostatic field measuring instrument, which is used to measure the electrostatic value of the surface of objects and measure the ion balance degree of electrostatic elimination equipment. The shell is made of anti-static material and has a grounding buckle to ensure the correct and reliable measurement results, and the display of numbers and graphics is clear and clear. The electrostatic tester can also light up the panel to display lights in a dark environment. There is an ion balance measuring board to measure the residual voltage of the static elimination equipment, and the measuring range is +/-200V.

Electrostatic tester should be noted when measuring:
(1) Measurement instruments with high reliability and ease of use should be selected. Explosion-proof type should be selected for measuring instruments in explosive dangerous places.
(2) Read the instrument instructions carefully before measurement to understand its measurement principle and scope of use.
(3) Drop before the lake, adjust the sensitivity and select the range.
(4) Measurement analysis of the risk of detonation caused by measurement. Measurement should be carried out after the risk of ignition has been eliminated; Emergency measures should be considered in advance in the event of an accident.
(5) In order to prevent discharge during measurement, the probe of the measuring instrument should be slowly approached by the charged body. This should be true even for explosion-proof instruments.
(6) The same item should be measured several times, in the case of good reproducibility, take its average and maximum.
