Common problems of surface resistance tester
1. What is the difference between a portable surface resistance tester and a hundred bipolar surface resistance tester?
Because of its small size and easy portability, the portable surface resistance tester can test some conventional ESD products, so ESD is generally carried around. The two-stage electric rent tester is used to test the point-to-point resistance of the object surface. The measurement requirement is to measure the resistance between two points that are independent of the ground. The measurement result obtained by this measurement method is related to the processing of the measured object and the distance between the two probes. Therefore, the correct measurement should be selected The procedure knows that the test should be carried out under the same required measurement conditions each time.
2. The surface resistance tester measures resistance?
There are many models and brands of surface resistance testers. In order to measure the resistance of the object surface more accurately, it is recommended that you choose a tester with a voltage selection key. Such instruments will have better precision and accuracy. higher.
Many domestic joint ventures and wholly-owned enterprises use the standards of the International Electrotechnical Commission. In order to move closer to international standards, adapt to the requirements of international advanced electrostatic protection technology, and improve the integration of our national standards with international standards. The General Specification for Anti-static Capacitance Testing of In-Product Manufacturing and Application Systems is equivalent to adopting the test voltage regulations in IEC61340-5-1. If the user does not put forward insulation resistance safety requirements, we should perform the above test procedures when conducting resistance testing .
