Micro 570 Analyzer

The Micro 570 analyzer tests charging and starting systems, including the battery, starter and generator.
? When working with batteries, always exercise extreme caution and wear appropriate eye protection to avoid injury. ? When charging the battery based on test results, the battery must be fully charged. To obtain an accurate test result, the surface charge of the battery must dissipate before testing when you test the battery after charging. (See the following battery test results)
Micro 570 Keypad: The Micro 570 keypad buttons provide the following functions:
Battery Test Procedure
  1. Connect the tester to the battery.
    A. Connect the red clamp to the positive (+) battery terminal.
    B. Connect the black clamp to the negative (-) battery terminal.
    • Secure the clamps. If the message "CHECK CONNECTION" appears on the screen, secure the clamps again.
  2. The tester will ask whether the battery is "IN VEHICLE" or "OUT OF VEHICLE". Make your selection using the arrow buttons, then press ENTER.
  3. Select CCA and press the ENTER button.
    • CCA: Cold Cranking Amps, the SAE specification for starting batteries at -0.4°F (-18°C).
  4. Set the CCA value shown on the screen equal to the CCA value marked on the battery label by pressing the UP and DOWN buttons, then press ENTER.
    • The battery ratings (CCA) displayed on the tester must match the ratings shown on the battery label.
  5. The tester will perform the battery test.
  6. The tester displays the battery test results, including voltage and battery condition. Refer to the following table and perform the actions recommended by the Micro 570.

    GOOD BATTERY No action required.
    GOOD CHARGE The battery is in good condition.
    Charge the battery and use it.
    ? You must follow the instructions below when charging the battery and repeat the test, otherwise the test result may be inaccurate. (See "Battery Charging and Retest Method" below.)
    CHARGE AND RETEST The battery is not charged properly.
    • Charge and retest the battery.
    ? You must follow the instructions below when charging the battery and repeat the test, otherwise the test result may be inaccurate. (See "Battery Charging and Retest Method" below.)
    REPLACE BATTERY Replace the battery and retest the charging system.
    • An incorrect connection between the battery and the vehicle cables may cause "REPLACE BATTERY". Retest the battery after disconnecting the cables and connecting the tester directly to the battery terminals before replacing the battery.
    BAD CELL - REPLACE Charge and retest the battery.
    • If the Micro 570 recommends "REPLACE BATTERY", replace the battery and retest the charging system.

    [Battery Charging and Retest Method] Battery Charging: Set the battery charger to "Automatic Mode" (a mode in which the charging current decreases as the battery charges) and charge the battery until the charging current is close to zero or the charger alarms to indicate charging is complete. (Recommended minimum charging time: more than 3 hours in automatic mode)
    A. If the battery is not fully charged, the surface voltage of the battery will be high while the cold cranking amps (CCA) of the battery is low. If you test the battery in this condition, the tester may incorrectly evaluate that battery sulfation has occurred, because the amount of current in the battery is too low compared to the battery voltage. * Surface voltage: when the battery is charged, the electrolyte temperature rises and the chemical reaction becomes active, resulting in an excessive increase in battery voltage. It is known that it takes approximately one day for this elevated surface voltage to fully dissipate.
    Battery Test After Charging: Do not test the battery immediately after charging. Test the battery after the surface charge has dissipated, as specified in the following procedure.
    1. After charging the battery is complete, install the battery in the vehicle.
    2. Turn the IG key to the ON position, turn on the low beam headlights, and wait 5 minutes. (Discharge for 5 minutes)
    3. Turn off the headlights and the IG key and wait 5 minutes. (Wait 5 minutes after turning off the IG key)
    4. Disconnect the + and - cables from the battery, and then test the battery.
    • When submitting a battery claim, attach a printout of the battery test results.
    Starter Test Procedure
  7. After testing the battery, immediately press ENTER to test the starter.
