3 Terminology

3.1 surface resistance surfaceresistance In between the two electrodes of the sample surface the applied voltage and the power of time specified in the current flowing through the quotient between the two electrodes. Polarized in the two electrodes may be formed negligible. Note. The normal current flows mainly through a surface layer of the sample, but also flows through the components within the sample volume. 3.2 electrode electrodes Electrode testing equipment is generally used for communication with the test sample and to the sample collection device related information. this Specification tester electrode conductor has a certain shape, size and weight of the sample in contact.

4 Overview

Surface resistance tester is used to measure anti-static objects (such as. floors, work surfaces, clothing, etc.) surface resistance The special test equipment, the test voltage is generally 250V, 100V and 10V (or 9V) and the like. Surface resistance tester method commonly used at both ends of the electrode between the measured surface resistance was measured to determine The surface resistance value of the object. The measurement electrode is generally shaped hammer (hammer) electrode, which has a digital display Display Shows, the bar graph and a light emitting diode (LED) display. Digital display, an analog tester by measuring pointer displayed after the measured surface (resistance) applied voltage Generating current size, to determine the surface resistance value of the object by means of operation. Mainly by the test power, zoom ......
