OBDSTAR BT06 12V 24V Car Battery Tester user manual in English, including operation instruction and Results for charging system test.
Connect OBDSTAR BT06 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 voltage of the battery to be tested should be lower than 6.0 V or the normal test is unable to proceed; Press OK to continue.
Follow the prompt of the BT06 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.
Step6: Press ok to begin the test
Test results interpretation
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 the 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 malfunction.
No voltage output:
The generator voltage output is not detected. Table check whether generator connections and generator belts are normal.
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.
