➠ Turn on the machine.
➠ Connect both channels to the connectors X13, X15 or X16, pin1 respectively.
➠ Set the oscilloscope to "auto" (with trigger).
➠ With the help of the positioning switches of CH1 and CH2, move the oscilloscope ray of CH1
to the center of the screen and the oscilloscope ray of CH2 to the lower edge of the screen.
➠ Change the connection of CH1 to connector X13, X15 or X16 on pin 2 respectively.
➠ Change the connection of CH2 to connector X 13, X15 or X16 on pin 5 respectively.
➠ Set the trigger to "norm" and set the oscilloscope with "trigger" to a suitable triggering
threshold.
➠ Manually, move the appropriate axis back and forth.
– If you adjusted the read correctly, the following illustration will be displayed on the
oscilloscope screen:
