11. Before Sending for Repair
Use the following troubleshooting guide for hints on problems with instrument
operation.
When using the instrument, always check whether;
¡
The test probe connector is correctly plugged into the probe socket.
¡ The batteries are correctly installed.
¡ The batteries have enough power.
¡ The test leads for precision earth resistance measurement are correctly
connected to the instrument's terminals.
¡ There is no break in test leads or test probes.
CAUTION
¡ The instrument passed inspections and shipped in the best possible
condition. If any abnormal operations are noted because of aging, do not
use the instrument and return it for inspection and repair.
Condition Possible Cause
The meter does deflect in BATT
CHECK.
Check batteries are installed correctly.
"Power-on" indication LED does not
light up when the test button is
pressed on insulation resistance
ranges
Check batteries are installed correctly, or
check the test probe connector is correctly
inserted into the probe socket.
"Power-on" indication LED does not
light up on AC voltage range.
This is not a failure.
BATT CHECK results in "OK", but
the meter does not read on any
range
Check test leads for a break and replace them
if necessary.
On earth voltage ranges, "Power-
on" indication LED lights up before
the test lead connection is made. This is not a failure, but it is notifying the user
that the function selector switch remains set to
the earth voltage range.
On earth resistance ranges, "Power-
on" indication LED lights up and the
meter goes offscale at a press of a
button when the probe connector is
not plugged into the socket.
This is not a failure. The instrument will operate
properly after making correct test lead
connection.
On earth resistance ranges, "OK"
lamp does not light up
Check the test leads are correctly connected to
the instrument or to the auxiliary earth bars.
Check the auxiliary earth bars are stuck into a
moist part of the earth. If not, give enough
water.
Check the test leads for a break and replace
them if necessary.
