Tester Cables
The test cables that come with your analyzer are consumable items. Cables are like tires in that
the more you use them and the harder you drive them, the shorter their useful life. Here are a few
things you can do to protect your test cables from damage and premature wear:
Cleaning Clamps
• The grease, dirt, and sulfation that build up on battery terminals are highly corrosive and can
damage the clamps over time. Before connecting the clamps, ensure accurate test readings
and protect the clamps by cleaning the battery case and terminals using a wire brush and a
mixture of water and baking soda.
• Periodically clean the clamps using a mixture of baking soda and water, or a mild hand-soap,
and a small bristle brush.
• To protect the clamps from oil and dirt, clip them to the Clamp Tab on the back of the analyzer.

Handling Test Cables
• Always connect and disconnect the clamps to the battery by opening and closing the clamps.
Never pull on the test cables to remove the battery clamps. Pulling can damage the Y-junc-
tion, the cables, and the clamps to the extent that the analyzer may produce lower-than-
expected conductance readings or fail completely.
• Never carry the analyzer by the cables. Carrying the analyzer or swinging it by the cables puts
unnecessary strain on the cables and can result in premature failure. Handle the analyzer with
care to get the maximum use from the product.
Storing Test Cables
• Never wrap the cables around the analyzer; this puts unnecessary strain on the test cables.
Because the test cables are the “tires” of the analyzer, they have a certain life expectancy and will
wear out eventually. However, the abuse examples cited above are not covered under warranty. To
ensure the best performance and longest life of the test cables, attach and remove them with care,
and carry the analyzer and cables together.
If an inspection or a change in test results indicate that the test cables need to be replaced, call
