Battery Test
Select the battery test and press OK key to continue:
• Battery Type: select your battery type, usually is
"Regular Flooded".
• Input testing standard: the standard which you
can see the front of the battery, such as CCA,
BCI,DIN. If you cannot find any information about
the standard, you can choose GB standard.
Choosing GB standards would lead to a small
tolerance.
• Input rated capacity: you can see the starting
current standards in front of the battery, such as
BCI/300A.
• Then press OK key to start testing.
NOTE: For battery power loss (such as a vehicle for a
long time in standby, the battery is not charged in time,
forget to close the lights, doors create serious losses
of electric vehicle battery and cannot start, etc.), in the
actual test process can also be asked to replace the
battery. For this type of batteries, please consult the
battery manufacturers.
Cranking Test
After entering the se-
cond start system test
function, press OK
key.
Starting the engine as
prompted, tester will
automatically comple-
te the cranking test
and display the result.
Normally, cranking vol-
tage value below 9.6V
is considered abnor-
mal, and above 9.6V is
all right.
The test result of the
tester includes the ac-
tual cranking voltage
and actual cranking
time.
When cranking test is
abnormal, battery test
result shall also be
displayed at the same
time.
NOTE: This is for the convenience of the maintenance
personnel to quickly know the whole state of the star-
ting system according to the data. If the engine starting
cannot be detected, there may be no output of char-
ging voltage, you need to check the generator.
Charging Test
When entering the
Charging Test, the tes-
ter will indicate "Char-
ging Test".
NOTE: Do not switch
off the engine during
the test. All electrical
appliances and devices
are in the OFF state.
Turning ON or OFF any
electrical device on the
vehicle during the test
will affect the accuracy
of the test result.
Act accordingly to in-
crease the rotational
speed of the engine to
2500 revolutions, and
hold for 5 seconds.
The tester starts the
charging voltage test af-
ter detecting the increa-
se of revolutions.
When the test is com-
pleted, the tester dis-
plays the effective char-
ging volts, the result of
the ripple test and the
result of the charging
test.
Finally, check the con-
nection between gene-
rator and battery, then
retest.
