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.
The Micro 570 button on the key pad provide the following functions :
Connect the tester to the battery.
Red clamp to battery positive (+) terminal.
Black clamp to battery negative (-) terminal.
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.
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.
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.
Result On Printer | Remedy |
GOOD BATTERY | No action is required. |
GOOD RECHARGE | Battery is in a good state. Recharge the battery and use. |
CHARGE & RETEST | Battery is not charged properly. - Charge and test the battery again. (Failure to charge the battery fully may read incorrect measurement value.) |
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. |
Whenever filing a claim for battery, the print out 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.
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.

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.
Result On Printer | 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. |
The MDX-670P battery conductance and electrical system analyzer tests batteries as well as starting and charging systems for vehicle.
It displays the test results in seconds and features a built-in printer to provide a copy of the results.
Because of the possibility of personal injury, always use extreme caution and appropriate eye protection when working with batteries.
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.
Connect the red clamp to the positive (+) terminal and the black clamp to the negative (–) terminal.
For a proper connection, rock the clamps back and forth. The tester re¬quires that both sides of each clamp be firmly connected before testing. A poor connection will produce a CHECK CONNECTION or WIGGLE CLAMPS message. If the message appears, clean the terminals and reconnect the clamps.
Scroll to and select IN VEHICLE or OUT OF VEHICLE for a battery not connected to a vehicle.
Following an IN VEHICLE test you will be prompted to test the starting and charging systems.
Scroll to and select REGULAR FLOODED, AGM FLAT PLATE, or AGM SPIRAL where applicable.
If the vehicle equipped with ISG function, select the AGM FLAT PLATE.
Scroll to and select the battery’s rating system.
Mostly, the CCA value is marked on the battery label, but sometimes marked EN or SEA value. Select one of them.
CCA: Cold Cranking Amps, as specified by SAE. The most common rating for cranking batteries at 0 ºF (–17.8 ºC).
EN: Europe-Norm
SEA: Society of Automotive Engineers, the European labeling of CCA
Set the selected rating value displayed on the screen to the value marked on the battery label by pressing up and down arrow buttons.
Press ENTER to start test.
After several seconds the tester displays the decision on the battery’s condition and the measured voltage. The tester also displays your selected battery rating and the rating units.

For an in-vehicle test, the display alternates between the test results and the message “PRESS FOR STARTER TEST.
Before starting the test, inspect the alternator drive belt. A belt that is glazed or worn, or lacks the proper tension, will prevent the en¬gine from achieving the rpm levels needed for the test.
Press the ENTER button to proceed with the starter test.
Start the engine when prompted.
The tester displays the decision on the starter system, cranking voltage, and cranking time in milliseconds.

Result On Printer | Remedy |
NO PROBLEMS | System is showing normal output from the alternator. |
NO OUTPUT | No alternator output detected. - Check all connections to and from the alternator, especially the connection to the battery. If the connection is loose or heavily corroded, clean or replace the cable and retest. - If the belts and connections are in good working condition, replace the alternator. (Older vehicles use external voltage regulators, which may require only replacement of the voltage regulator.) |
LOW OUTPUT | Alternator does not supply charging current to battery and electrical load to system fully. - Check belts and alternator and replace as necessary. |
HIGH OUTPUT | 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. |
