Battery Test Procedure
- Connect the tester to the battery.
- Red clamp to battery positive (+) terminal.
- Black clamp to battery negative (-) terminal.
CAUTION:- Connect clamps securely. If "CHECK CONNECTION" message is displayed on the screen, reconnect clamps securely.
- The tester will ask if the battery is connected "IN-VEHICLE" or "OUT-OF-VEHICLE". Make your selection by pressing the arrow buttons; then press ENTER.
- Select CCA and press the ENTER button.NOTE:
- CCA: Cold cranking amps, is an SAE specification for cranking batteries at -0.4°F (-18°C).
- Set the CCA value displayed on the screen to the CCA value marked on the battery label by pressing up and down buttons and press ENTER.NOTE:
- The battery ratings (CCA) displayed on the tester must be identical to the ratings marked on battery label.
- The tester will conduct battery test.
- The tester displays battery test results including voltage and battery ratings.
Refer to the following table and take the appropriate action as recommended by the Micro 570.
Battery Test Results
Result On Printer Remedy GOOD BATTERY No action is required. GOOD RECHARGE Battery is in a good state.
Recharge the battery and use.
* You have to follow instruction below when you charge battery and retest, otherwise test result can be inaccurate. (See 'Charge and Retest method after battery charge' below.)CHARGE & RETEST Battery is not charged properly. - Charge and test the battery again.
* You have to follow instruction below when you charge battery and retest, otherwise test result can be inaccurate. (See 'Charge and Retest method after battery charge' below.)REPLACE BATTERY Replace battery and recheck the charging system. - Improper connection between battery and vehicle cables may cause "REPLACE BATTERY". Retest the battery after removing cables and connecting the tester to the battery terminal directly prior to replacing the battery.
BAD CELL-REPLACE Charge and retest the battery. - If the Micro 570 recommends "REPLACE BATTERY", replace the battery and recheck the charging system.
[Charge and Retest method after battery charge]
Battery charge
Set battery charger to "Auto Mode" (the mode under which charging current drops as the battery is charged.) and charge battery until charging current becomes close to zero or the charger alerts you with an alarm when charging is completed.
(Minimum charging time recommended: More than 3 hours with Auto Mode)
- If battery is not fully charged, battery surface voltage will be high while the amount of current charged (CCA) in battery is low. If you measure the battery under this condition, tester may misjudge that battery sulfation occurred because the amount of current in battery is too low in comparison with battery voltage.
* Surface voltage: When battery is charged electrolyte temperature increases and chemical reaction becomes active resulting in an excessive increase of battery voltage.
It is known to take about one day for this increased surface voltage to subside completely.
Battery Test after charging
Do not test battery right after the charge. Test battery after battery surface voltage has subsided as instructed in the following procedure.
- When battery charge is complete, install the battery in the vehicle.
- Put IG key to ON position and turn on head lamp with low beam, and wait 5 minutes. (Discharge for 5 minutes)
- Turn off the head lamp and IG key, and wait 5 minutes. (Waiting for 5 minutes after the IG key OFF)
- Remove +, - cable from the battery and then test the battery.WARNING:
- Whenever filing a claim for battery, the printout of the battery test results must be attached.
Starter Test Procedure
- After the battery test, press ENTER immediately for the starter test.
- Start the engine.
- Cranking voltage and starter test results will be displayed on the screen.
Refer to the following table and take the appropriate action as recommended by the Micro 570.
Starter Test Results
Result On Printer Remedy CRANKING VOLTAGE NORMAL System shows a normal starter draw. CRANKING VOLTAGE LOW Cranking voltage is lower than normal level. - Check starter.
CHARGE BATTERY The state of battery charge is too low to test. - Charge the battery and retest.
REPLACE BATTERY Replace battery. - If the vehicle does not start though the battery condition of "GOOD BATTERY" is displayed, check wiring for open circuit, battery cable connection, starter and repair or replace as necessary.
- If the engine does crank, check fuel system.
NOTE:- When testing the vehicle with old diesel engines, the test result will not be favorable if the glow plug is not heated. Conduct the test after warming up the engine for 5 minutes.
Charging System Test Procedure
- Press ENTER to begin charging system test.
- The tester displays the actual voltage of alternator.
Press ENTER to continue.
- Turn off all electrical load and rev engine for 5 seconds by pressing the accelerator pedal. (Follow the instructions on the screen)
- The message that engine RPM is detected will be displayed on the screen. Press ENTER to continue.
- If the engine RPM is not detected, press ENTER after revving engine.
- The tester will conduct charging system test during loads off.
- Turn on electrical devices (air conditioner, lamps, audio and etc.). Press ENTER to continue.
- The tester will conduct charging system test during loads on.
- Rev engine for 5 seconds by pressing the accelerator pedal. (Follow the instructions on the screen)
- The message that engine RPM is detected will be displayed on the screen. Press ENTER to continue.
- If the engine RPM is not detected, press ENTER after revving engine.
- Turn off electrical devices (air conditioner, lamps, audio and etc.). Turn the engine off.
- Charging voltage and charging system test results will be displayed on the screen.
Shut off the engine and disconnect the tester clamps from the battery. Refer to the following table and take the appropriate action as recommended by the Micro 570.
