Product Description

Product overview:

Micro-Ohmmeter (Loop resistance tester/Low Resistance tester) is the special test equipment for measuring the contact resistance and loop resistance of some devices such as switch, circuit interrupter, and transformer and so on. It adopts the typical four-wire method of measurement which helps get the DC resistance through the following steps: outputting a DC current, applying the current to the tested body by linking its two terminals, and measuring the voltage drop when the current goes through the tested body, then dividing the current by the voltage. In addition, it mainly consists of constant current source, preamplifier, A/D converter, indicating device and so on.


Features and Functions:

1. The four-terminal wiring method effectively eliminates the influence of the resistance of the test line on the test results
2. High test current
3. The test current is from a high-precision high-current constant-current power supply, without manual adjustment, and the test is fast and accurate
4. High power constant current switching power supply technology, high output voltage, wide measurement range
5. With real-time printing function of test data
