32 Clamp-on Ground Resistance Tester Model 6416
6.1.2.2 Measurement Results
First Screen:
Once the measurement has stabilized,
the display shows the first screen, which
indicates:
■
The leakage current (l).
■ The loop impedance (Z) referenced to
the chosen frequency.
The impedance is measured only if the
leakage current is less than 10 A. In
the 10 to 40 A range, only the current is
displayed; the NOISE symbol blinks and
the impedance is replaced by dashes.

Second Screen:
Press ► to display the second screen,
which indicates the contact voltage
(product ZxI).
Figure 6-3
Third Screen:
Press ► to display the third screen,
which indicates the values of R and L.
The loop inductance and loop resistance
are displayed.
When the inductive component is
negligible* with respect to the resistive
component, the symbol R=Z is
displayed, and only the impedance is
displayed; the inductance is replaced by
dashes.
* R > 25
Ω or R[ Ω ] / L[H] > 10
