OPERATIONS INSTRUCTION
When battery voltage is lower than normal test voltage, the test
result cannot check the battery state properly. It will show
“Re-test after charging”. At this time, please charge the
battery, then test it.
When battery voltage is too high or the vehicle is starting, the
test can’t be proceeded. It will show “The voltage is too high.
Please turn off the engine! Please turn on the headlights in 3
NOTE:
Connect the red test clamp with battery positive (+) and the
black clamp with negative (-), the tester will power on automati-
cally. Battery voltage below 6.0V can’t be tested properly, then
press any key to continue.
Select according to the tester display:
(1) Test standard:
The standard which you can read from the top or front of the
battery , such as CCA, IEC, DIN. If you can’t find any informa-
tion about the standard, AH of battery capacity can be used as
a reference. Choose similar battery standard, and it will cause
small error.
(2) Rated capacity:
You can read the cranking current standard in the top or front
of the battery, such as CCA 370.
(3) Press ENTER key to start testing.
For small battery, the lower resistance it is, the healthier the
battery is (except short-circuit). Resistance can be used as a
reference for the battery state.
