The Micro 570 Analyzer (Canada only)

The Micro 570 Analyzer provides the ability to test the charging and starting systems, including the battery, starter and alternator.

? Because of the possibility of personal injury, always use extreme caution and appropriate eye protection when working with batteries.

? When charging battery by test result, Battery must be fully charged.

To get accurate test result, battery surface voltage must have subsided ahead before test when you test battery after charged. (See following Battery Test Results)

Keypad

The Micro 570 button on the key pad provide the following functions :

Battery Test Procedure

Connect the tester to the battery.

A.	Red clamp to battery positive (+) terminal.

B.	Black clamp to battery negative (-) terminal.

Connect clamps securely. If "CHECK CONNECTION" message is displayed on the screen, reconnect clamps securely.

2.	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.

CCA : Cold cranking amps, is an SAE specification for cranking batteried 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.

The battery ratings(CCA) displayed on the tester must be identical to the ratings marked on battery label.

5.	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.

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 that charging current drops as the battery charges.) and charge battery until charging current down close to zero or the charger alerts you with an alarm when charge is complete.

(Minimum charging time recommended: More than 3 hours with Auto Mode that explained above)

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 become active resulting in an excessive increase of battery voltage.

It is known that it takes approximate one day to subside this increased surface voltage completely.

Battery Test after charge

Do not test battery right after the charge. Test battery after battery surface voltage has subsided as instructed in the following procedure.

(1)	When battery charge is complete, install the battery in the vehicle.

(2)	Put IG key to ON position and turn on head lamp with low beam, and wait 5 minutes. (Discharge for 5 minutes)

(3)	Turn off the head lamp and IG key, and wait 5 minutes. (Waiting for 5 minutes)

(4)	Remove +, - cable from the battery and test battery.

Whenever filing a claim for battery, the print out of the battery test results must be attached.

Starter Test Procedure

7.	After the battery test, press ENTER immediately for the starter test.

8.	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 is not started 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.

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

10.	Press ENTER to begin charging system test.

11.	The tester displays the actual voltage of alternator. Press ENTER to continue.

12.	Turn off all electrical load and rev engine for 5 seconds with pressing the accelerator pedal. (Follow the instructions on the screen)

13.	The message that engine RPM is detected will be displayed on the screen. Press ENTER to continue.

14.	If the engine RPM is not detected, press ENTER after revving engine.

15.	The tester will conduct charging system test during loads off.

16.	Turn on electrical loads (air conditioner, lamps, audio and etc). Press ENTER to continue.

17.	The tester will conduct charging system test during loads on.

18.	Rev engine for 5 seconds with pressing the accelerator pedal. (Follow the instructions on the screen)

19.	The message that engine RPM is detected will be displayed on the screen. Press ENTER to continue.

20.	If the engine RPM is not detected, press ENTER after revving engine.

21.	Turn off electrical loads (air conditioner, lamps, audio and etc). Turn the engine off.

22.

Charging voltage and charging system test results will be displayed on the screen.

Shut off engine end disconnect the tester clamps from the battery. Refer to the following table and take the appropriate action as recommended by the Micro 570.

Charging System Test Results

Remedy

CHARGING SYSTEM NORMAL / DIODE RIPPLE NORMAL

Charging system is normal.

NO CHARGING VOLTAGE

Alternator does not supply charging current to battery.

-	Check belts, connection between alternator and battery and replace belts or cable or alternator as necessary.

LOW CHARGING VOLTAGE

Alternator does not supply charging current to battery and electrical load to system fully.

-	Check belts and alternator and replace as necessary.

HIGH CHARGING VOLTAGE

The voltage from alternator to battery is higher than normal limit during voltage regulating.

-	Check connection and ground and replace regulator as necessary.

-	Check electrolyte level in the battery.

EXCESS RIPPLE DETECTED

One or more diodes in the alternator is not functioning properly.

-	Check alternator mounting and belts and replace as necessary.
