Easy and fast clamp-on operation. No need for cables
or auxiliary rods/stakes.
Large LCD display screen that can be read in bright
sunlight.
Measures ground resistance from 0.025Ω to 1550Ω.
Direct reading of continuity and ground loop resistance.
Measures ground leakage or phase current from
0.2mA to 35A.
Large jaw opening to accommodate a variety of
conductors.
Indication of high noise content that may affect
readings.
Lightweight...only 750g (1.65lbs), yet exceptionally
rugged for regular field use.
Hold function for difficult to reach installations.
Auto-off to save on battery power.
Configure high and low alarms with audible indication
for fast field checks.
On board storage of test results (up to 8180 records).
Calibration check loop to insure proper operation.
Rugged, yet lightweight storage case contains complete
testing kit.
USB interface for download of test data for later analysis
(DET20C).
