3. OPERATING INSTRUCTIONS
BATTERY TEST
IMPORTANT: During the rst use of this tester, you will notice a little smoke and/or a burning smell. This is normal and will stop after a short burn-in period. Also, during regular use,
the metal housing of the unit will get hot enough to burn skin or cause property damage; carry by the handle. Neither of these factors will affect the performance of your tester.
1. Turn off the ignition, all accessories and any loads.
2. Clean the battery terminals.
3. Clip the red clamp to the positive (POS, P, +) battery terminal.
4. Clip the black clamp to the negative (NEG. N, -) battery terminal.
6V BATTERY ANALYSIS
1. Read the meter and conrm the battery voltage is in the green “GOOD” area (see illustration).
2. Press and hold the load switch “on” for a maximum of 10 seconds and read the meter with the load still on. The needle should remain in the green area. If it doesn’t,
the battery is weak or bad.
CAUTION: To prevent overheating, allow tester to cool for 5 minutes before depressing the load switch again, if further testing is required.
12V BATTERY ANALYSIS
1. Find the Cold Cranking Amps (CCA) range on the meter (see illustration) that matches the CCA rating of the battery being tested.
2. Press and hold the load switch “on” for a maximum of 10 seconds and read the meter with the load still on. Then, refer to Table 1.
CAUTION: To prevent overheating, allow tester to cool for 5 minutes before depressing the load switch again, if further testing is required.
