(2) Press <▲><▼>to select maximum load system test as the picture below:
(3)After selecting to get access to the below screen
(4)After operating as step (3) , press <ENTER> to display the maximum load
system test screen as the picture below: As can be seen in the picture current
test voltage is 12.86V, standard voltage is 12.80V,(for 24V system
<DI-215C>, standard voltage is 25.60V), the lowest voltage is 12.30V.
(5)Read the lowest value. If it is high than 12.80V,(for 24V system
<DI-215C>, the voltage is over 25.60V), the system runs normally.
(6)Press <ESC> to return step (2).
5-4-3 There are some problems in the system
★ If the value is lower than 12.80V,(for 24V system <DI-215C>, the voltage
is under 25.60V), please check the engine belt if damaged and the wires if
exist short circuit.

(2) Then set the date and report number. If not need it , press <ESC> to skip.
(3) Press <ENTER> or <ESC> to print the report.
(4) After printing the report, the tester is set back to the step(3) in the 5-2
storage battery test.
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.
