Battery Test - OTC 3181 Mode D'emploi

BATTERY TEST

Battery Temperature
The most accurate test results will be obtained when battery tempera-
ture is at approximately 70° F. If testing battery between 70° and 40° F,
add 0.1 volt for every 10° F below 70° F. If testing a battery between
70° F and 100° F, subtract 0.1 volt for every 10° above 70° F.
Connect Tester to Battery (See Figure 1)
1. Connect the black clamp to the battery negative (-) post.
2. Connect the red clamp to the battery positive (+) post.
Make sure both sides of each clamp make good contact with the battery
posts. If required, rock the clamps back and forth to
improve connection.
3. Press and hold the LOAD SWITCH for 10 seconds.
4. Hold the LOAD SWITCH and read the meter (See Figures 2 or 3).
5. Release the LOAD SWITCH immediately after reading the meter.
6. Disconnect the red clamp from the battery.
7. Disconnect the black clamp from the battery.
If REPLACE indication is suspected due to the battery being completely
discharged because of lights or other accessories being left on, charge battery
to full capacity and retest before deciding to replace the battery.
