1.3 Product Function
 Battery test is mainly targeted to analyze the battery health status to calculate the actual cold cranking
capability of the battery and the aging extent, which provide reliable analysis evidence for the test and mainte-
nance of the battery. It notifies the user to replace battery in advance when the battery is getting aged.
 Cranking test is mainly to test and analyze the starting motor. Through testing the actual required cranking
current and cranking voltage of the starting motor, it can find out whether the starting motor works fine. There
are several reasons why the starting motor is abnormal: lubricating system fault causing the starting loaded
torque increasing or rotor friction of the starting motor causing the increasing friction of the starting motor itself.
 Charging test is to check and analyze the charging system, including generator, rectifier, rectifier diode,
etc., thus tofind out whether the output voltage of the generator is normal, the rectifier diode works fine and the
charging current is normal. Suppose one of the above mentioned parts is not in normal situation, it will lead to
overcharge or incomplete charge of the battery, thus the battery will be quickly damaged and also greatly short-
en the using life of other loaded electrical appliance.

2 Operating Instruction
2.1 Battery Test
2.1.1 Before Testing
 Clean battery poles with metal wire brush and alkaline cleaner to avoid the tolerance caused by oil and dust to
the test result.
 For Group31 or side-installed battery, connect and fix the terminal wiring connector. Otherwise, inaccurate test
result will be caused due to wrong installation or dirty or bad wiring connectors.
 While testing, ensure none of the in-vehicle electrical appliance is on, doors are closed and the ignition key is
in OFF status.
 Connect the red test clamp with battery anode and the black test clamp with cathode.
2.1.2 Check Connection
Shake the clamps back and forth to make sure they are well connected. Tester requires the two clamps are well
connected with the battery poles; otherwise, the test cannot go on. When enter the battery test program, screen
prompts "Check Connection" (See below picture).
Do clean the poles and re-connect in the right way.
2.1.3 Reverse Connection
Tester has reverse connection protection function. When clamps are reversely connected, tester will prompt
"Reverse Connection" (See below picture), but it damages neither the tester nor the automotive load.
NOTE: For parallel connected batteries, break off the cathode connection first, then do single test to each
battery. Suppose cathode connection is not cut off, there will be error in test result.

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.

2.3.2 Charging Test Result:
 Charging Volt: Normal. The generator output normal, no problem detected.
 Charging Volt: Low. Check drive belt of the generator whether slip or running off. Check the
connection between generator and battery is normal or not. If both of the drive belt and the
connection are in good condition, follow the manufacturer's suggestion to eliminate generator
fault.
 Charging Volt: High. Since most of the vehicle generators are using internal regulator, the
generator assembly has to be replaced.(Some old style cars are using external regulator, then
directly replace the regulator.) The normal high volt of the voltage regulator is maximum
14.7±0.5V.If charging volt is too high, it will overcharge the battery. Therefore, the battery life will
be shortened and troubles will be caused.
 No Volt Output. No generator volt output is detected. Check the generator connection cable, the
drive belt of generator and engine whether normal or not.
 Diode Test: Through the test of charging current ripple, tester will find out whether the diode is
normal or not. When ripple volt is too high, it proves at least one diode is damaged. Check and
replace the diode.
