Application Field and Troubleshooting of 100A Loop Resistance Tester
Application:
1. It is suitable for testing the contact resistance of the main contact of high and low voltage switches.
2. Suitable for testing DC resistance of high and low voltage cables.
3. It is suitable for testing any ultra-low resistance without inductance.
The test process is automatically executed by microcomputer program control, with text prompts and good human-computer interface, high precision, single key operation, simple and easy to operate.
Troubleshooting and maintenance of circuit resistance tester:
The instrument is subject to high and low temperature and various aging tests before leaving the factory, so it is not easy to fail. Under the following circumstances, you can solve the problem yourself:
1. Connect the circuit, power on, no display, fuse is blown, replace the fuse.
2. After pressing the test button, the resistance value displays abnormally:
Follow the prompts on the display screen to check
A: The circuit is not connected, and+I and - I are not firmly connected
B: The resistance to be measured is too large, or the jaw is in poor contact with the product to be measured
C: +V and - V are not well connected, and the resistance value is abnormal
The above conditions can detect the circuit wiring and clear the jaw contact
