As can be seen in the picture current test voltage is 12.36V, standard voltage
is 9.6V,(for 24V system<DI-215A>, standard voltage is 16V), the lowest
voltage is 12.30V.
(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.(for 24V system<DI-215A>, the voltage should be higher than 16V
when staring up the engine)
(5)Press <ESC> to return step (2).
5-3-3 instruction of engine system test
★
the lowest voltage higher than 9.6V (for 24V system, the reading is over
16V) means good.
★
the lowest voltage lower than 9.6V (for 24V system, the reading is under
16V) means no good.
Please check the relative connections, wire and engine. Also the
terminals of the battery should be checked if rusted.

5-4-1 preparation
★
Please star the engine firstly.
5-4-2 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.

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.
