Ground Bond Resistance and Loop/Line Resistance Verification
Procedure
Follow these steps to verify the ground bond resistance and loop/line resistance functions,
1. Two-wire ground bond resistance test:
a. Connect the ground bond/loop/line resistance decade output terminals PE and N to a
standard multimeter (8588A). Use a four-wire connection and set the 8588A for four-
wire measurement.
b. Set the series resistance parameter in the ground bond resistance setup to zero.
c. Select the
Z GND
function on the Product.
d. Push the
Mode
softkey and select
Resistance 2W
.
e. Push
O
.
f. Select each available nominal value from 25 m
Ω
to 1.7 k
Ω
with the rotary knob, cursor
keys, or numerical keypad. Measure their resistance and compare that measurement
with the value shown on the Product. Compare the measurement on the Product to the
limits in
2. Four-wire ground bond resistance test:
a. Connect the ground bond/loop/line resistance decade output terminals PE and N to the
8588A +I and -I terminals. Connect the ground bond/loop/line resistance decade output
terminals Z GND SENSE to the 8588A +
Ω
SENSE and -
Ω
SENSE terminals. Use a four-
wire connection and set the 8588A for four-wire measurement.
b. Set the series resistance parameter in the ground bond resistance setup to zero.
c. Select the
Z GND
function in the Product. Push the
Mode
softkey and select
Resistance 4W
.
d. Push
O
.
e. Select each available nominal value from 25 m
Ω
to 1.7 k
Ω
with the rotary knob, cursor
keys, or numerical keypad. Measure their resistance and compare that measurement
with the value shown on the Product. Compare the measurement on the Product to the
limits in
