NOTE:
If "Replace" resulted from IN-VEHICLE mode, it might be the reason that vehicle cable is not
well connected with the battery. Ensure to cut off the cable and retest the battery under
OUT-OF-VEHICLE before making a decision to replace battery.
After testing, if need to return, press “RETURN” key to directly return to the startup interface. If it is
"OUT-OF-VEHICLE" test state, press OK key, it will print the test result. If it is "IN-VEHICLE" test
state, press OK key will bring to Cranking Test.
2.2. Cranking Test
Connect with current clamp in advance. Under bad connection, tester will not test the actual
cranking amps accurately.
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, higher than 9.6V is OK.
Test result includes actual cranking voltage, actual cranking amps, and actual cranking time.
When cranking test is abnormal, battery test result will also be displayed at the same time. See
below image
After testing finished, do not shut down the engine, press OK key to enter Charging Test.
2.3 Charging System and Rectifier Diode Test
2.3.1 Test Procedures
When enter the charging test, tester will prompt "Charging Test?" Press OK key to start the
charging test.
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.
Tester will do the following tests in a sequence: For ripple test, tester will display the real time ripple
and meanwhile, shows ripple volt and charging volt values at the bottom line.
After the ripple test, tester will automatically start the loaded voltage test.
Loaded Volt Test takes about 3 seconds, then it hints "Step on accelerator to increase engine
rotating speed". Operate accordingly to increase the engine rotating speed to 3000turns or
above, and keep for 5 seconds.
Tester starts the charging volt test after increase rev detected. The result displays the effective
charging volts, ripple test result and charging test result.
If no increase rev detected, it shall be the fault of generator regulator or connection with battery
failed. Tester will try 3 times to further detect, if still failed, it will skip the increase rev detect and
the test result displays "No Volt Output". Check the connection between generator and battery,
then retest.
