Operating

Polarity test

The red LED lights up when the test probes rest on a positive contact within the rated voltage range. The green LED lights up on
the test probe coming into contact with a negative pole. The lead is considered to be interrupted should no LED light up in one of
the above instances.

Continuity testing

The earth lead has to be used for this test!
By using the test probe, which supports the earth lead, you can test the conductivity between wires or components which have
been disconnected from the vehicle's electrical system. The green LED should light up when current flows between wires.

Component test

By deploying the measurement probe and earth lead, the user can activate the components to be tested without attaching them to
the vehicle's electrical system. Light, fan and fuel pumps, for instance, can be tested with this function. For this, please follow the
following procedure:
1. Connect the earth lead to the negative pole of the component.
2. Connect the measurement probe to the positive pole of the component. The fact of the green LED lighting up means that
the component is conductive.
3. When the green LED lights up, press the polarity switch forward and then release it immediately. You can continue with the
test when the LED changes from green to red. However, the fact of the green LED going out and the red LED not lighting
up or the circuit breaker being triggered means that the tester is overloaded. This could be due to the following:
-
-
The circuit-breaker regenerates itself within 60 seconds from being triggered.
