Product Description

Loop Resistance Tester

Darui Electric recommends for you:

Loop Resistance TesterAccording to the requirements of the preventive test procedure for power equipment "DL/T 596 — 1996", the test current for the conductive circuit resistance test of various switchgear shall not be less than 100A. Due to reasons such as oxidation of contact surfaces and poor contact tightening, the contact resistanceincreases. When a large current flows through, the temperature at the contact point rises, which accelerates the oxidation of the contact surface, further increasing the contact resistance. If this continues, serious accidents may occur. Therefore, it is necessary to measure the contact resistance frequently or regularly.

Technical Parameters

1. Measurement range: 0~4mΩ (50A gear) 0~2mΩ (100A gear) 0~1.33mΩ (150A gear) 0~1mΩ (200A gear)

2. Test current: DC50A, 100A, 150A, 200A fixed output

3. Measurement accuracy: ±(0.5% rd+2d)

4. Continuous working time: 5s~599s

5. Display mode: large screen Chinese LCD display

6. Communication method: RS232 serial port

7. Working power supply: AC220V±10% 50Hz

8. Total power: 1200W

Operating Procedure

1. Connect the wiring according to the four-terminal method.

2. Turn on the power.

3. Press the measurement key (if the current display A value is less than 100A, it can be corrected through the panel current fine-tuning).

4. After the measurement value is displayed, save the data.

5. After the measurement, please turn off the power.

6. Please take care of the test clamps.
