Cleaning

Periodically wipe the case with a damp cloth and mild

detergent. Do not use abrasives or solvents. Dirt or

moisture in the terminals can affect readings. Allow time

for drying before using the Tester.

Testing the Batteries

The Tester continuously monitors battery voltage. If the

low battery icon (B) appears on the display, there is

minimal battery life left. To test the batteries:

1. Turn the rotary switch to the b position with no

probes inserted.

2. Press the blue button to initiate the fully loaded

battery test. The voltage function displays clear and

the measured battery voltage is shown in the primary

display for 2 seconds, the voltage display then

returns.
