Operating Principle
Intelligent Circuit Resistance Tester adopts current and voltage method test principle, also called four-wire test technology, principle shows as below picture 1.
Picture 1, Test Principle
Current source have two-end"I+,I- (called 'I' shape), supply current for being tested resistance Rx, current value can be read by amperemeter I,voltage of Rx"V+,V-" (called 'V' shape) read by voltmeter V. So to calculate resistance value by the measurement of I and V.

Operating Procedure
VI,Operating Procedure
Normal operating process is shutdown cable connection, power on, settings, test, data storage, printing, shutdown and remove cable, totally it is 7-setp.
(1) Cable connection
Under shutdown status, please connect GND cable, power cable, test cable. Refer to the cable connection diagram in 'help' menu. Tighten the big current clamp, small current clamp must tight touch with being tested object, two small voltage clamps are in inner side of current clamp.
