OPERATING INSTRUCTIONS

7. Unit of measure
Insert the plug of the instrument to the cigarette lighter socket, read the reading on the display, and observe the LED indication as well as the bar
indication in the battery icon.
By referring the following table, you can determine the charge level of the 12v or 24 batteries.
Numerically Displayed value
12V Battery 24V Battery
13.0V - 18.0V 26.0V - 38.5V
12.4V - 12.9V 24.8V - 25.9V
12.1V - 12.3V 24.1V - 24.7V
11.7V - 12.0V 23.3V -24.0V
"LLL" appears if the "LLL" appears if the
voltage is <11.7V. voltage is 23.2V - 18.1V.
Note: If the battery voltage is more than 38.5V, the display will show the over-range indicator "EEE" and you should ask a qualified technician to check
the battery and the automotive electronic system.

NOTE

1. Remove from the cigarette lighter socket when not in use.
2. Don't use the instrument to measure a voltage higher than 38.5V.
3. Before use, verify the instrument's operation by measuring a known automotive storage battery.
Don't operate the instrument if it operates abnormally.
4. Do not operate the instrument around explosive gas, vapor, or dust.
