Note: Please do not shut down the engine during the test. Other
electrical equipment should be turned off. If any electrical
appliances in the car are switched on or off during the test, it can
affect the accuracy of the test results.
Under different engine operating conditions, the battery voltage will
be different. Under normal conditions, the charging voltage will not
be lower than the minimum value of 13.3V, and it should not be
higher than 15.0V at high speeds.
Charging voltage is too low:
•
The charging voltage of the charging system is insufficient.
•
Please check the generator drive belt for slippage or
disconnection, and check whether the line connection between
the generator and the battery is normal.
•
If the transmission belt and line are well connected, please
follow the suggestions of automobile and motorcycle
manufacturers to eliminate the generator fault.
Charging voltage is too high:
•
The generator output voltage is too high.
•
Since most car generators use built-in regulators, you need to
replace the generator assembly (some older cars use external
regulators, please replace the regulators directly).
•
The usual high voltage limit for automotive regulators is 14.7V.
Excessive charging voltage can overcharge the battery, which
shortens the battery life and causes it to malfunction.
Maximum Load Test
In the main menu, press the up and down keys to select the load
test, and press the OK key to enter the test, notice:
10
Start the engine at this time, wait for the operation to stabilize, and
then press OK to display the test status.
When all electrical appliances are turned on, under normal
circumstances, the power supply capacity of the generator is
sufficient, and the charging voltage will be greater than 12.8V. If it
is lower than this voltage value, the reason may be that the
generator output current is insufficient, the generating power is
reduced, or the appliance Excessive load or leakage occurs; if the
electric appliances on the car are artificially increased, the voltage
will also decrease.
Printing Data
•
battery test printing, After the battery system test is completed,
there is a "print" item in the lower right corner of the screen. At
this time, press the shortcut key of "select Print function", the
printer of the tester will start to work, and the test result data of
the battery system will be displayed on the print paper.
