Resistance to
Ground Test Problem:Electrical leakage is creating an unstable
output from the instrument.
Cause:Water contamination in the load sensors or
cables.
Remedy:
Step 1. Tie together the load sensor excitation (2),
signal (2) and ground (1) wires.
NOTE: Be careful NOT to include the two C2 wires.
Step 2. Use a megohmmeter and measure the resis-
tance between all five wires tied together
and the load cell metal body. The measured
value should be 5,000 megohms or more.
Step 3. Replace the load cell if the cell fails both
tests.
WARNING WHEN USING A MEGGER DO NOT EXCEED
50 VOLT RANGE.
If the sensor fails this test, remove the ground wire
and test with only the four live leads.
Replace the load cell if the cell fails both tests.
If the sensor passes the test, an insulation problem in
the cable is most likely.
