Digital Micro Ohm Meter , Resistance Meters , DC Low Resistance Tester
I. Product Introduction :
UT620 series are used to measure DC low resistance through 4-wire method. Some of their features are: Comparison function to determine if the device is in good condition, unknown wire length calculation (FT/M); two-way data transmission by USB interface; built-in rechargeable lithium battery.
UT620 can be used in narrow space for on-site troubleshooting, such as metal coating resistance/motor and small transformer winding resistance measurements, earth system joints/welding points/power distribution cabinet bus and lead connection inspections and more.
II. Features
1. Improved measurement method which improves accuracy by counter-balancing contact resistance of leads
