Introduction of battery test operation
Connect device with the battery
Put the red and black clamp to the battery to be tested. Red clamp
for positive, black clamp for negative. It will show start-up
interface on the screen.
The v oltage of the battery to be teste d should be lower than 6.0 V
or the normal test is unable to proceed; Press OK to continue.
According to the prompt of the device, select in proper
order
Step1: Choose the testing state
It refers to if the battery is inside the vehicle with load connected.
If so, choose [Inside vehicle]. If not, choose [outside vehicle].
Step2: Choose charge state
It refers to if the charge of the battery is finished. If so, choose
[After charge]. If not, choose [Before charge].
Step3: Choose battery type
It refers to the battery type. Choose [Normal battery] in general.
Step4:Choose input standard
It refers to the factory marked standard for the battery, which is
shown on the right above or the front battery. Choose the marked
standard, such as CCA, JIS and etc.
If there is no standard shown, please select GB standard and input
the Ah value to test. The error will be less when selecting GB
standard.
Step5: Choose rated capacity
It refers to factory starting current standard, which is shown on the
right above or the front battery. Such as 55B24.
Step6: Press ok to begin the test
Test results interpretation
Tip:
Notice: For some batteries in deep lack of power (the vehicle is not
used for a long time, batteries are not charged in time; battery is in
deep lack of power because of not turning off lamp and door that
can not start the vehicle and etc), there will be a prompt “please
replace the battery”. For this kind of battery, please consult with
the battery manufacturer fist and replace and charge the battery
according to the method given by the manufacturer, and then begin
the test.
Start system test
Step1: After the battery test is finished, please press [OK] to enter
starting system test if the testing state is inside vehicle as shown
below.
Step2: Start the engine according to the prompt and the device will
finish the starting system test automatically and show the result.
Step3: Test result includes start time, start voltage and voltage
state.(In general, start voltage lower than 9.6v is abnormal, higher
than 9.6v is normal.)
Step4: If the starting system test is abnormal, the battery test
results are displayed.
In this way, the maintenance personnel can quickly determine the
overall condition of the starting system according to this data.
Charging system test
(1) After starting system test is finished, please press [OK] to
enter Charging system test and operate according to the
prompt and “please seep up to 3000 RPM and keep for 5s”
(2) After test is finished, the device will show charging voltage,
on-load voltage and diode ripple as shown below.
Notice: If the device can not detect the engine speed, there is
probably something wrong with the engine regulator or the
connection breakdown with t he battery. If the device can not detect
the charging voltage, the device can skip the engine speed test,
then the result will show “No voltage input”. Please check the
connection between engineer and battery and then test again.
Results for charging system test
Charging voltage: normal
The charging system shows that the output of the generator is
normal and no problems are detected.
Charging voltage: low
Insufficient charging voltage of charging system
Please check whether the generator belt is skidding or
disconnecting, check whether the connection between the
generator and the battery is normal.
If the transmission belt and circuit is connected well, please
troubleshoot the generator according to the manufacturer's
suggestion.
Charging voltage: high
The voltage for generator output is too high.
As most generators in the cars use a built-in regulator, it needs to
replace the generator assembly (some older cars which use external
regulators, please replace the regulator directly).
The limit of usual high voltage limit in a car regulator is 14.7v.
Charging too high will make the battery go through charging, thus
shortening the life of the battery and causing it to malfunctio n.
No voltage output:
The generator voltage output is not detected. Table check whether
generator connections and generator belts are normal.
Diode testing:
The tester can detect whether the diode is normal by charging
current waveform. If the diode wave voltage is too high, then at
least one diode has been damaged, please check and replace the
diode. So far, the test is completed.
