7. Remove personal metal items such as rings, bracelets, necklaces and
watches when working with a lead acid battery. It can produce a short circuit
current high enough to weld a ring or the like to metal causing a severe burn.
PREPARING TO TEST:
1. Be sure area around battery is well ventilated while battery is being tested.
2. Clean battery terminals. Be careful to keep corrosion from coming in contact
with eyes.
3. Inspect the battery for cracked or broken case or cover. If battery is damaged,
do not use tester.
4. If the battery is not sealed maintenance free, add distilled water in each cell
until battery acid reaches level specified by the manufacturer. This helps
purge excessive gas from cells. Do not overfill.
5. If necessary to remove battery from vehicle to test, always remove ground
terminal from battery first. Make sure all accessories in the vehicle are off to
ensure you do not cause any arcing.
OPERATION & USE:
Note: Each time you connect the tester to a battery, the tester will run a quick
cable verification to ensure a proper connection through the output cables to
sensors in the clamp jaws. If the connection checks out OK, the tester will
proceed to the Home Screen. If the connection is poor, the display will show
"CHECK CABLE". In this case, check cable connections for visible signs of
damage, as you may need to re-connect the clamps to the battery or replace the
cable end.
BEFORE TESTING:
1. Before you test a battery in a vehicle, turn off the ignition, all accessories and
loads. Close all the vehicle doors and the trunk lid.
2. Make sure the battery terminals are clean. Wire brush them if necessary.
Clamp the black load lead to the vehicle negative battery terminal. Clamp the
red load lead to the vehicle positive battery terminal. Please clamp on the lead
part of the terminal only. Clamping on the iron part of the terminal will lead to
wrong test results.
