Note
Throughout this manual “rotary switch” refers to the rotary function
switch on the Meter.
Basic Maintenance
This basic maintenance section of the manual contains tests and procedures that
require no equipment other than the Meter and some consumables such as fuses and
batteries. Also, internal access is limited to the battery and fuse compartment.
Cleaning
When cleaning is necessary, wipe the Meter with a damp cloth and mild detergent.
Do not use abrasives or solvents. Dirt or moisture on the terminals can affect
readings.
Testing the Batteries Under Load
XW
Warning
To avoid electrical shock or personal injury, replace the
batteries as soon as the battery indicator (
b
) appears. A
weak battery can cause false readings.
Before testing the batteries, turn the Meter to
B
. If
b
appears on the display, the
batteries are weak; replace them. If the display is blank, batteries may not be present
in the Meter, or they may be completely discharged; install new batteries.
The following procedure tests the batteries under load:
1.
Depress the
h
while turning the rotary switch to
INSULATION
.
2.
Read the display. The displayed voltage should be 5.2 V or greater. If voltage is
lower than 5.2 V, replace the batteries and repeat this test.
