Clamp-on Ground Resistance Tester Model 6417
9
2.2 Features
■
Simple and fast clamp-on operation - no leads, no auxiliary rods or spacing
requirements
-
Ammeter:
Current measurements from 0.2mA to 40A.
-
Loop ohmmeter:
Measurement of loop impedances from 0.01 to 1500
W
.
The ohmmeter function makes allowance for the presence of inductances
in the loop, making impedance measurements more accurate at low
values.
-
Contact voltage:
The contact voltage is determined by calculating the
product of the loop impedance and leakage current. The value found is an
upper bound on the voltage between the measurement point and earth,
since the impedance taken into account is that of the whole loop.
