23-B Surface Resistance Tester

Overview:

Model 23-B surface resistance tester is composed of medium and large-scale integrated circuits. The meter has high output power, high short-circuit current value and many output voltage levels (four voltage levels for each model). The working principle is that the battery in the machine as a power supply by the DC/DC conversion of DC high voltage from the E pole out of the test article to reach the L pole, thus generating a current from the E to the L pole, after the I / V conversion by the divider to complete the operation will be measured directly by the LCD display of the insulation resistance value.
