To avoid damaging the battery test cable, always hold the ridged part of the cable connector (as
shown in the photo) when inserting and removing the cable.
Display Problems
The display does not turn on:
•
Check the connection to the battery.
•
The analyzer’s internal batteries may need to be replaced.
The display flickers or is dim:
•
The analyzer’s internal batteries may need to be replaced.
Internal Batteries
The tester uses six AA, 1.5-volt batteries (alkaline recommended) to allow testing of batteries down
to 1 volt and supply power while the menu is active. On the mainscreen you can see an internal
battery charge indicator; this is purely an indicator to show when batteries are close to a necessary
replacement.
Replacing The Internal Batteries
1.
Turn the analyzer face down.
2.
Use a Phillips screwdriver to remove the screw securing the door to the battery compartment.

3.
Lift the door at the tab and place it aside.
3.
Touch the toothless jaw of the clamp with the other probe tip. Wiggle the battery test cables.
The resistance reading should be less than 1 Ω.
4.
Repeat the test for the “TEETH” side of the circuit, this time touching the jaw with teeth. Insert
the other probe tip into the “teeth” pin hole. Wiggle the battery test cables. The resistance
reading should be less than 11 Ω.

Connecting The Battery Test Cable
To prevent damage to the analyzer’s circuitry, do not connect
the analyzer to a voltage source greater than 30 Vdc.
To connect the battery test cable to the analyzer align the cable connector with the analyzer’s
housing. Hold the part of the cable connector as shown and firmly insert the connector into
analyzer’s receptacle. Do not twist.
