Sawtooth start position
– Before measuring the sawtooth with a test oscilloscope
(e.g. HM1000), set the test oscilloscope to the following
settings:
DC input coupling.
Connect 10:1 probe to the test oscilloscope.
– Set test oscilloscope to 2 ms/div and 20 mV/div (0.2 V/div in
combination with the 10:1 probe).
– Set test oscilloscope to automatic trigger mode and move
the trace with Y- Pos. to a horizontal graticule line in the
lower half of the screen and remember the GND (0V) positi-
on e.g. using the ground symbol displayed by the readout.
– Locate and identify RV4005 on TB-Board.
– Locate and identify check point socket M9001 on X Y-
Board.
– Locate and identify pin 7 at socket M9001.
– Connect probe reference connector (crocodile clip) with
chassis.
– Connect probe tip with pin 7 of socket M9001.
– Set instrument to 1 ms/div.
– Adjust RV4005 so that the sawtooth start position is at
