NOTE
The adjustment procedures assume that the instrument had
once been properly adjusted in the factory and adjustments are
required due to component aging or the replacement of defective
components.
Before starting each adjustment procedure, set the oscilloscope
to the following basic settings:
– POWER pushbutton pressed (IN position).
– All other pushbuttons (Out Position!).
– Rotate the three variable controls (TIME/DIV. and VOLTS/
DIV.) to their (calibrated) detent positions.
– Set TIME/DIV. switch to 0.2 ms/div.
– Set both VOLTS/DIV switches to 5 mV/div.
– Rotate the HOLD OFF knob fully counter clockwise.
– Set trigger coupling lever to AC.
– Set all other controls to their midrange positions.
If different settings are required, it is specifi ed in each adjust-
ment.
