Product Description

High Voltage Switch Loop Resistance Tester

Dary Electric recommends:

High Voltage Switch Loop Resistance Tester, measurement range: 0-1999μΩ resolution: 1μΩ.

Introduction

High Voltage Switch Loop Resistance TesterAccording to the requirements of the new "Power Equipment Handover and Preventive Test Procedures", the measurement of the conductive loop resistance of various switchgear must have a test current of not less than 100A. To this end, our factory has designed and developed a new generation of intelligent loop resistance tester products according to the new procedures. This product is suitable for testing the contact resistance value of the main contacts of high and low voltage switches, and the DC resistance value of high and low voltage cable lines. The JD-100 A intelligent loop resistance tester uses 100A constant current output. The maximum output voltage reaches 10V (2-3 times that of conventional instruments), and thin test leads can be used, greatly reducing the labor intensity of field testers. The test process is fully controlled and implemented automatically by a single-chip microcomputer, with high accuracy and good repeatability. Single-button operation is simple and easy. Test data is displayed on the LCD and results are printed. Suitable for different working environments.

This machine has a built-in 100A switching power supply to achieve constant current 100A two-loop real-time tracking test. Ensure correct test results.

Operation Procedure

1. Connect the wires according to the four-terminal connection method.

2. Turn on the power.

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

4. After the measurement display value, if you need to save the data, press the measurement/print button for three seconds to print the data.

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

6. Please take care of the test clamps.
