Clamp-on Ground Resistance Tester Model 6416 29
6.1.2.2 Measurement Results
First Screen:
Once the measurement has stabilized, the
display shows the  rst screen, which indicates:
- The leakage current (I).
- The loop impedance (Z) referenced to the
chosen frequency.
The impedance is measured only if the leakage
current is less than 10A. In the 10 to 40A range,
only the current is displayed; the NOISE symbol
blinks and the impedance is replaced by dashes.

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 > 25W or R[W] / L[H] > 10
