Midtronics PowerSensor Micro400 Instruction Manual page 2

*** Caution ***
Because of the possibility of personal injury, always use
extreme caution when working with batteries.
Prior to Testing
• 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 of this manual
before testing.
Connecting The Tester
• Connect red clamp to positive terminal.
• Connect black clamp to negative terminal.
• To ensure a proper connection, rock the clamps back
and forth. The tester requires both sides of the clamp
to be firmly connected prior to testing. A poor
connection will prevent testing and a CHECK
CONNECTION message will appear. If this occurs,
clean the terminals and reconnect.
Testing Procedure
•
Use the yellow arrows to scroll to
the battery's CCA rating.
650 CCA (SAE)
SET CCA RATING
• Press the green start button to test.
• After testing, if the battery's
temperature is 32
press the blue temperature
compensation button to get a
compensated test result.

Battery
Condition
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 The 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.
Retest the battery after disconnecting the cables before replacing.
• If the SYSTEM NOISE message appears, make sure all vehicle
accessory loads are off and the ignition switch is in the off
position. Retest.
If the SYSTEM NOISE message continues after several retest
attempts, disconnect the battery cables and retest.
Troubleshooting
If the display does not illuminate:
• Check connection to the battery.
• 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 ie. 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 charging, replace the
battery.
