1. Battery Test
Select the battery test and press OK key to continue
Battery Type: select your battery type, usually is “Regular Flooded”
Input testing standard: the standard which you can see the front of the battery ,such as CCA、BCI、DIN. If you can’t find
any info about the standard, you can choose GB standard. Choose GB standards would lead little tolerance.
Input rated capacity: you can see the starting current standards in front of the battery
Then press OK key to start testing.

2. Cranking Test
Starting the engine as prompted, tester will automatically complete the cranking test and display the result.
Normally, cranking voltage value lower than 9.6V is regarded as abnormal and it is OK if it is higher than 9.6V.
Test result of the tester includes actual cranking voltage and actual cranking time.
When cranking test is abnormal, battery test result will also be displayed at the same time.

3. Charging Test
When enter the charging test, tester will prompt "Loaded testing"
Note: Do not shut down the engine during the test. All electrical appliance and device are in OFF state. Turn on/off any
electrical appliance in the vehicle during the test will affect the accuracy of the test result.
Operate accordingly to increase the engine rotating speed to 2500turns, and keep for 5 seconds.
Tester starts the charging volt test after increase rev detected.
After the test finished, tester displays the effective charging volts, ripple test result and charging test result.

4. Review Data
After entering the forth function, then press OK key you can view the final test result.

5.Print Data
You can print out the test result with built-in printer.

6. Export Data
