Basic Maintenance

This basic maintenance section of the manual contains tests and procedures that require
no equipment other than the Tester 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 Tester 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

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.
The Tester continuously monitors battery voltage. If the low battery icon (B) appears
on the display, there is minimal battery life left. Before any performance test, check the
batteries and replace if necessary.
The following procedure tests the batteries under load:
1. Turn the rotary switch to the b position with no probes inserted.
2. Press the blue key to initiate the fully loaded battery test. The voltage function
display clears and the measured battery voltage is shown in the primary display
for two seconds, the voltage display then returns. The displayed voltage should
be within 5.5 to 6.2 V. If voltage is lower than 5.2 V, replace the batteries and
repeat the test.

Replacing the Batteries and/or Fuse

Replace the fuse and batteries as shown in Figure 1. Follow the steps below to replace the
batteries.
