Product description
Practical tester of 13-pole sockets and plugs of trailers, caravans and towing vehicles. 12V power supply.
Product parameters:
- measurement of 13-pole plugs and sockets, fault location.
- the tester cannot be used for towing device sockets with their own control unit (CANBUS)
Technical parameters:
- vehicle on-board voltage: 12V
- 9× LED indicator to display the functionality or non-functionality of the circuit

- approval: CE according to ISO1724
Trailer lighting measurement procedure:
- insert the plug from the trailer lighting into the tester and press the yellow button on the side of the device.
- if everything is OK, all LEDs will light up. Each LED indicates the function of one electrical circuit.
- if one LED is not lit, there may be a faulty connection, a broken wire or a broken bulb.
- if not a single LED is lit, the –12V wire (ground) is probably broken, or the battery in the device is discharged.
