Component Activation Solely With Positive Pole; Component Activation Solely With Negative Pole; Trailer Light Test - TESTBOY TB 60 Bedienungsanleitung

Component activation solely with positive pole

Components being tested by the user can be supplied through the TB 60 with exclusively positive voltage.
1. 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.
2. When the green LED lights up, press the polarity switch forwards and then release it immediately. 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 component either has a short-circuit or was attached with the polarity reversed.
-
The component is a high-efficiency component.
-
The circuit-breaker regenerates itself within 60 seconds from being triggered.

Component activation solely with negative pole

Components being tested by the user can be supplied through the TB 60 with exclusively negative voltage.
1. Connect the measurement probe to the negative pole of the component. The fact of the red LED lighting up means
that the component is conductive.
2. When the red LED lights up, press the polarity switch to the rear and then release it immediately. However, the fact
of the red LED going out and the green LED not lighting up or the circuit breaker being triggered means that the
tester is overloaded. This could be due to the following:
The component either has a short-circuit or was attached with the polarity reversed.
-
The component is a high-efficiency component.
-
The circuit-breaker regenerates itself within 60 seconds from being triggered.

Trailer light test

The following procedure must be followed when examining the light system of a trailer:
1. Connect the earth lead to the earthing of the trailer.
2. By using the measurement probe, a connection can now be set up to the lighting system at the trailer plug con-
nector. The light can be tested by now pressing the polarity change-over switch forwards.
3. The green LED lights up when the probe comes into contact with the negative pole.
