switch S302 to the position 20 mV/div., the
sensitivity adjustment potentiometer R348 to
the position “X CAL.“ and the switch S303 to
the position “0 “. Set the trace approximately
to the centre of the screen, the height of the
rectangle being about 3 divisions. Trim the
wave-form of the rectangle to an optimum by
adding Cr capacitors in parallel with C341.
(The value of Cr is 330 or 680 or 820 p F .)

Adjustment of Input Capacity of the Basic
Range of X I Input
Set the switch S302 to the position 20 mV/div.
and the switch S301 to the position “r r z : “.
Apply a rectangular-wave voltage of about
150 mV from a generator to the X I input
(F301) via a calibrator. Rectangular waves
now appear on the screen and their shape
can be adjusted to an optimum by means of
the capacitor C333. The switch S303 must be
in its “0 “ position during this procedure.

Adjustment of Input Capacity of the Basic
Range of X2 Input
The procedure is the same as described in the
previous paragraph, the capacitor C334 being
used to trim the rectangular wave-form.

to the X I input (F 3 0 1 j. Set the switch S301 to
the position “

switch S301 to the position “0 “ and the switch
S303 to the position “ r

Apply a rectangular-wave voltage to the “X I “
input (F301) via a calibrator. Use the control
elements to adjust the image to be sufficiently
bright and sharp and to keep the size of the
image about 3 divisions throughout the adjust­
ment procedure. Trim the shape of the rectan ­
gle to an optimum by means of the capacitors
as indicated in the table below for the indivi­
dual ranges.
Repeat the procedure for the “X2“ input.
