Intended purpose
The digital battery tester is designed solely for displaying the charge status (capacity) of 12 V batteries in vehicles. It is suitable for all
vehicles with a standard 12 V socket or cigarette lighter. Only for vehicles with lead-acid battery!
In addition, the digital battery tester has a built-in protection circuit which deactivates connected consumers if the capacity of the battery
drops to 5 % or less.
Operating the battery tester
To operate the battery tester, connect the plug contact to the 12 V socket of your vehicle and adapt the angle of the plug in accordance
with the space available to you. The display automatically shows the current capacity of the vehicle battery in percent and the green LED
on the top of the device lights up. If the display shows FL (FULL) there is voltage, the charge voltage of the alternator, that is higher than
the battery voltage. The charge voltage depends on the vehicle type and the type of alternator.
Operation of mode with automatic switch off
If the digital battery tester is installed in your vehicle in accordance with the paragraph above, you can use it as a battery protector. Connect
the 12 V connector of the consumer (fan, working light, radio receiver, etc.) to the 12V socket on the front of the digital battery tester.
Caution:
Only consumers with a maximum power consumption of 8 Amperes may be connected.
Then you can use the consumer as usual. The current charge state (capacity) can be read off the display at any time.
The connected consumer (e.g. the working light) discharges the battery in your vehicle. If the capacity of the vehicle battery drops to 5 %,
the digital battery tester deactivates the 12 V outlet and thus switches the connected consumer off. In addition, the green LED on the top
of the device and the red LED - switch off indicator - will light up.
The battery of your vehicle is thus protected from the risk of deep discharging.
Even when the switch off is activated, the residual capacity of your battery is shown in the display.
Maintenance
The digital battery tester does not need maintenance when it is used correctly.
Use a dry cloth to clean.
After connecting a consumer with too much power or a defective consumer (short-circuit):
In the event that the digital battery tester does not output information to the display and the LEDs on the top of the device do not light
up, remove the device from the 12 V on-board power system of your vehicle and check the installed 10 Ampere fuse of the digital battery
tester. Proceed as follows:
• Turn the knurled screw at the top of the 12 V plug anti-clockwise until it comes away from the plug and then remove.
• The 10 Ampere fuse is exposed and can be pulled out of the plug
• Check the fuse and replace, if necessary, with another fuse of the same strength. Never bridge the fuse.
• Screw the knurled screw back onto the plug.
Disposal
The digital battery tester is an electrical device. A defective electrical device must be disposed of at the local collection point for
electronic and electrical waste and should not be introduced into the household waste.
