200 A Safety Ground Tester With Built-In Thermal Printer
SGT-200 - Manta Test Systems (Doble)
The Vanguard SGT-200 Safety Ground Tester is a 200A DC micro-ohmmeter designed specifically to measure the resistance of protective in-service grounding and jumper cable assemblies. The SGT-200 can measure the resistance of the grounding cables, clamps and ferrules. The measured resistance values can be compared against the calculated values (using the ASTM 2249-03 standard) and a Pass/Fail result can be printed along with the measured resistance values. Since the SGT-200 uses a DC current, there is no need to uncoil the cable under test. It can be conveniently tested in its coiled state in a much smaller testing enviornment.
