BATTERY SYSTEM TESTER
5-3 Charging system test
5-3-1 Preparation
Please star the engine firstly.
5-3-2 Procedure of operation
(1)When the engine is working, connect the red clamp to the
positive polar of the battery, and the black one to the negative
polar. Make sure they are well connected in order to avoid
affected result.
(2)Speed the engine to 3000 rpm.
(3)Press <
▲
><
▼
> to select charging system test as the picture
below:
(4)After selecting the test item, press <ENTER> to display the
charging system test screen as the picture below:
The picture of generator output highest voltage indicates the
current test voltage is 13.88V, the highest voltage is 14.08V, and
the lowest voltage is 13.75V.
(5)Press <
▲
><
▼
> to select highest output screen and lowest
output screen.
(6)As in the process, when the generator output the wrong
highest voltage or lowest voltage, the instrument will appear the
generator output current voltage generator output highest voltage
generator output lowest voltage
(3)After selecting the test item, press <ENTER> to display the
activation load test screen as the picture below:
Press <
▲
><
▼
> to select “The current instant voltage” or
“Minimum starting voltage”. As can be seen in the picture
current test voltage is 12.88V, standard voltage is 9.6V, and the
lowest starting voltage is 10.95V.
(4)Star the engine to make the tester automatically record the
lowest voltage in this process. Normally the voltage of battery
will be higher than 9.6V in this process.
As the starting process, recorded the lowest voltage is lower
than 9.6V, the instrument will beep and flash screen.
(5)Press <ESC> to return step (2).
5-2-3 Instruction of engine system test
★
The lowest voltage higher than 9.6V means good.
★
The lowest voltage lower than 9.6V means no good.
Please check the relative connections, wire and engine.
Also the terminals of the battery should be checked if rusted.
