Midtronics PowerSensor MICRO 400 - Digital Battery Analyzer Manual

BEFORE THE TEST

Because of the possibility of personal injury, ! always use extreme caution when working with batteries. Follow all BCI (Battery Council International) safety recommendations.

• Clean battery posts or side terminals with a wire brush.
• For group 31 or side-post batteries, install and tighten lead terminal studadapters (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 andthe 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. Bothsides of the clamp must be firmly connected before testing and a CHECK CONNECTION message will appear. If this occurs, clean the terminals and reconnect.
  

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'ssurface 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 corrosionbetween 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 accessoryloads 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). Fullycharge 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 otherhigh-current device. If so, move away and retest.
• If no source of noise is identified, fully charge the battery and retest. If themessage appears after the battery is charged, replace the battery.
