Product Description

Standardized Equipment for Loop Resistance Testing
Loop Resistance Tester Calibrating System
 
Product I ntroduction
 
Standardized Equipment for Loop Resistance Testing Loop Resistance Tester Calibrating System
The Standard Device for Loop Resistance Testing incorporates a fixed and reliable high-power standard resistor box. The instrument's resistance value is stable, dependable, and highly accurate. It utilizes precision insulation oil internally for electrical isolation, effectively eliminating testing interference. It allows direct calibration of loop resistance testers with current ratings of 100A/200A, ensuring a simple testing process and reliable results.

The instrument employs the four-wire method, establishing a one-to-one correspondence with the device under test (loop resistance tester). After testing the device, the results are printed and compared with the standard indication of this instrument. This allows for the calculation of the actual error of the device under test.
