How to Use
- Connect the red test clamp to the battery anode and the black clamp to the cathode. The tester will power on automatically. If the battery voltage is below 7.0VDC, it cannot be tested properly. Press the OK key to continue.
- Using the UP/DOWN keys on the tester, you can choose from the following options:
- Battery Test
- Cranking Test
- Charging Test
- Review Data
- Print Data
- Export Data to Computer
(1) Battery Test
Select "Battery Test" and press the OK key to continue:
- Battery Type: Select your battery type, typically "Regular Flood".
- Input testing standard: Select the standard indicated on the front of the battery (e.g., CCA/BCI/DIN). If no standard is found, choose the GB standard. Using the GB standard may result in slight tolerance differences.
- Input rated capacity: Enter the starting current standard found on the battery (e.g., BCI/300A).
- Press the OK key to start the test.
Note: For batteries with significant power loss (e.g., due to prolonged disuse, insufficient charging, or forgotten accessories like lights), the tester might prompt "Please replace the battery." For such cases, consult the battery manufacturer before proceeding with testing.
Example Test Prompt:
Charging Test
START ENGINE
Cranking Test
After starting the engine as prompted, the tester will automatically complete the cranking test and display the results. Typically, a cranking voltage below 9.6V is considered abnormal, while a voltage higher than 9.6V is normal. The test results include the actual cranking voltage and cranking time.
Example Test Display (RPM Detection):
Charging Test
RPM DETECTRD
Example Test Result (Normal Cranking):
Charging Test
TIME: 1758 ms
CHANKING: NORMAL
12.56V
If the cranking test is abnormal, the battery test results will also be displayed simultaneously. This feature allows maintenance personnel to quickly assess the overall condition of the starting system.
Example Test Result (Abnormal Cranking):
Charging Test
TIME: 1020 ms
CHANKING: Low
19.12V
(3) Charging Test
Upon entering the "Charging Test," the tester will display "Loaded testing."
Example Test Prompt:
Charging Test
LOADED TESTING
*****
Note: Do not shut down the engine during the test. Ensure all electrical appliances and devices are in the OFF state. Turning any electrical appliance on or off during the test can affect the accuracy of the results.
Follow the instructions to increase the engine rotating speed to 2500 RPM and maintain it for 5 seconds.
Example Instruction Display:
Charging Test
Increase RPM to 2500
r/min and keep it 5
seconds.
Press ENTER to
continue.
The tester begins the charging voltage test after detecting the increased RPM.

TESTING
***
After the test concludes, the tester displays the effective charging voltage, ripple test result, and the overall charging test result.
Example Test Result Display:
Charging Test
Loaded 13.97V
Unloaded 14.23V
Ripple 15 mV
CHARGING NORMAL
NOTE: If no RPM increase is detected, it indicates a fault with the generator regulator or the battery connection. The tester will attempt detection three times. If it continues to fail, it will skip the RPM detection and display "No Volt Output." Check the connection between the generator and the battery, then retest.
Charging Test Result Explanations:
- Charging Volt: Normal. The generator output is normal, with no detected problems.
- Charging Volt: Low. Check the generator's drive belt for slippage or misalignment. Verify the connection between the generator and the battery is secure. If both the drive belt and connections are in good condition, consult the manufacturer's recommendations for resolving generator faults.
- Charging Volt: High. Many vehicle generators use internal regulators. The normal high voltage for a voltage regulator is typically 14.7 ± 0.5V. If the charging voltage is too high, it can overcharge the battery, leading to a shortened battery lifespan and potential issues.
- No Volt Output. No generator voltage output is detected. Check the generator connection cable, the generator's drive belt, and the engine for normal operation.
- Diode Test: Through testing the charging current ripple, the tester determines if the diodes are functioning correctly. A high ripple voltage indicates that at least one diode is damaged. Check and replace the diode as needed.
