ROTEX 600 XTPRO: Service & Maintenance Manual - rev. 1.1
BE AWARE: Because all tester probes have a non zero internal resistance, which varies
depending on the model and may be in the same order of magnitude as the quantity
being measured, the following procedure is recommended:
1. Measure the internal resistance of the probes by short-circuiting them with each
other;
2. Measure the resistance of the power resistor.
3. The true resistance value is obtained by subtracting the short-circuit resistance of
the probes from the measured value.
(4) As for step (2) but with an oscilloscope between pins 6 and 3 of connector CN1 on the
alternator interface board.
(5) As for step (5) but with the oscilloscope between pins 6 and 3 of connector CN1 of the display
CPU board.
(6) As for step (2) but with an oscilloscope between pins 6 and 3 of panel connector CN11.
