CAUTION: Because of the possibility of personal injury,
always use extreme caution when working with batteries.
!
Follow all BCI (Battery Council International) safety
recommendations.
BEFORE THE TEST
• Clean battery posts or side terminals with a wire brush.
• For group 31 or side-post batteries, install and tighten lead terminal stud
adapters (included). Failure to properly install stud adapters, or using
stud adapters that are dirty or worn may result in false test results.
• If testing in the vehicle, make sure all vehicle accessory loads are off and
the ignition is in the off position. Read the "Testing In The Vehicle" section
before testing.
CONNECTING THE ANALYZER
• Connect red clamp to positive terminal.
• Connect black clamp to negative terminal.
• To ensure a proper connection, rock the clamps back and forth. Both
sides of the clamp must be firmly connected before testing and a CHECK
CONNECTION message will appear. If this occurs, clean the terminals
and reconnect.
Use the ARROW buttons to scroll to the
battery's CCA rating.
Press the green START button to test.
After testing, if the battery's temperature is
32 O F / 0 O C or below, press the blue
TEMPERATURE compensation button to get
a compensated test result.
BATTERY TEST RESULTS
The Micro400 will display one of the following results with the measured
voltage and available power.
GOOD BATTERY: Return to service.
GOOD-RECHARGE: Fully charge the battery and return to service.
CHARGE & RESET: Fully charge the battery and retest. Failure to
fully charge the battery before retesting may cause false readings.
REPLACE BATTERY: Replace battery.
BAD CELL-REPLACE: Replace battery.
TESTING IN-VEHICLE
• Turn on the highbeam headlights for one minute to remove the battery's
surface charge, then wait at least one minute to allow the voltage to
recover before starting the test.
• A REPLACE reading may be the result of a poor connection or corrosion
between the vehicle's battery cables and the battery. Before replacing,
retest the battery after disconnecting the cables.
• If the tester displays "SYSTEM NOISE", make sure all vehicle accessory
loads are off and the ignition switch is in the off position. Retest.
If the SYSTEM NOISE message reappears after several retest attempts,
disconnect the battery cables and retest.
TROUBLESHOOTING
If the display does not illuminate:
• Check the connection to the battery.
• The battery may be too low to power the tester (below 5.5 volts). Fully
charge the battery and retest.
If the tester displays SYSTEM NOISE message when the battery is not
connected to the vehicle:
• You may be testing too close to a source of noise, i.e., a charger or other
high-current device. If so, move away and retest.
• If no source of noise is identified, fully charge the battery and retest. If the
message appears after the battery is charged, replace the battery.
