1. Battery Test (In Vehicle / Out of Vehicle)
This test assesses the overall health and charge level of the battery.
- From the Main Menu, select "Battery In Vehicle" or "Out Of Vehicle" depending on your setup.
- Follow the on-screen prompts. The tester will display results such as:
- Healthy: Percentage of battery health.
- Charge: Percentage of battery charge.
- Internal R: Internal resistance of the battery.
- Rated: The rated Cold Cranking Amps (CCA) of the battery.
- CCA: Measured Cold Cranking Amps.
- Voltage: Current battery voltage.
- The display will indicate if the battery is "GOOD BATTERY", "GOOD, RECHARGE", "BAD CELL, REPLACE", or "REPLACE".

2. Cranking Test
This test evaluates the starting performance of the battery and the cranking system.
- Select "Cranking Test" from the menu.
- The tester will prompt you to "START ENGINE".
- Start the vehicle's engine. The tester will automatically detect RPM and perform the test.
- Results will include cranking time and voltage during cranking, indicating if cranking is "NORMAL" or if there are issues.
3. Charging Test
This test checks the vehicle's charging system (alternator) to ensure it is properly charging the battery.
- Select "Charging Test" from the menu.
- Follow the on-screen instructions, which may involve revving the engine to certain RPMs.
