7. Press F1 Start to read the earth ground resistance
of the ground rod. Less than 25 Ω is typically
considered good.
Leakage/Resistance
LEAKAGE
The LEAKAGE measurement applies 150 VDC to the
pair under test to detect intermittent resistance faults
that normal VOM tests cannot detect.
To conduct a leakage measurement, perform the fol-
lowing steps:
1. Connect the test leads: black to tip, red to ring, and
green to ground.
2. Move the rotary knob to the LEAKAGE/OHMS
position.
The Leakage display is the default display.
The leakage measurement for a single pair appears in
the LCD. The measurement updates continuously. The
leakage test also has the option to reverse the polarity
of the 150 VDC by pressing F3 REV.
For best results, leave the polarity in either direction for
at least 15 seconds. Then change it again and continue
to check the readings. A sudden drop in the resistance,
or readings that waver or change from one polarity to
the other, is a sign of galvanic corrosion breakdown.
Also the tip-to-ground and ring-to-ground measure-
ments should be rechecked for any change after the
polarity reversal.
