Description

XHHL***0/***0  Loop Resistance Tester

• Suitable for testing contacts resistance of  kinds of  breaker,GIS,bus bar,welding,and cables.
• According to the requirements of , the test current shall be not less than to **0A in every switching device conductive loop resistance measurement. According to this new regulations, a new generation of intelligent loop resistance tester products shall be designed and developed, the product is suitable for testing main contact resistance value of low voltage switch, and the DC resistance of the high and low voltage cabling. Intelligent loop resistance tester applies **0A constant current output. 

Functions:

• 1. The current test meets the requirements of national standard about loop resistance test.
• 2. The output voltage is high, measurement range is wide.
• 3. Test current is from the **0A high-precision constant current power, which doesnt need to manually adjust, and the test is quickly and accurately.
• 4. Using the four-terminal connection method, effectively ruled out the effect of test line resistance.
• 5. Test has a quick speed and good stability, and it displays data in about *0 seconds.
• 6. The operation is simple, light weight, with microcomputer print, suitable for field work.
