Loop Resistance Tester
Darui Electric recommends:
Loop Resistance TesterAccording to the requirements of the preventive test procedure for power equipment "DL/T 596 — 1996", the conductive circuit resistance test of various switchgear, the test current must not be less than 100A. Due to contact surface oxidation, poor contact tightening, and other reasons, the contact resistanceincreases. When 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.
Transportation and Storage
1. Transportation
When the equipment needs to be transported, it is recommended to use the company's instrument packaging wooden box and shock-absorbing items to avoid unnecessary damage during transportation and prevent unnecessary losses to you.
When the equipment is transported without a wooden box, stacking is not allowed. When using the company's instrument packaging box, the maximum stacking layer is two layers.
During transportation, the instrument panel should face upward.
2. Storage
The equipment should be placed indoors in a dry, dust-free, ventilated place without corrosive gases. Without wooden box packaging, stacking is not allowed.
When storing the equipment, the panel should face upward. Place moisture-proof items at the bottom of the equipment to prevent moisture.
Operating Procedure
1. Connect the wires 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 display value, save the data.
5. After the measurement, please turn off the power.
6. Please take care of the test clamps.
