6. FAQ
6-1 What is the measurement principle of this tester?
The battery will gradually aging with increase of time. The main reason
is that it can no longer generate some effectively chemical reaction because
of aging of the surface of the battery plate. That is why most of the batteries
can longer be used mainly. International Electric and Electronic Engineer
Association(IEEE)formally looks the Conductivity Test as one of the
standard of checking lead acid storage battery. It points out from IEEE
standard 1118-1996 that :Conductivity Test is used to test AC current
generated by putting the known frequency and amplitude AC signal to both
sides of the battery. AC conductivity value is the ratio of AC current signal
which keeps same phase with AC voltage and the AC voltage. This tester is
designed from this principle actually.

lowest voltage is 12.30V.
(4) Start up 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. (for 24V system, the voltage should be higher than 16V
when starting up the engine).
(5) Press <ESC> to return step (2).
5-3-3 start-up load test instruction
★
the lowest voltage higher than 9.6V(for 24V system, the reading is over
16V) means the start-up load system is good.
★
the lowest voltage lower than 9.6V (for 24V system, the reading is below
16V) means the system need to check.
Please check the relative connections, wire and engine. Also the
terminals of the battery should be checked if rusted.

5-4-1 preparation
◆ Please start up the engine firstly.
5-4-2 procedure of operation
(1) When the engine is working, connect the red clamp to the positive
terminal , with the black to the negative. Make sure all connections are well
contacted to ensure the accurate test.
(2) Press <▲><▼>to select maximum work load test as the picture below:
