Postup je stejny jako u pfedchoziho odstavce.
Optimślni tvar obdelnikń dostavime kondenzś-
torem C234.
Adjustment of Input Capacity of the Basic
Range of Y2 Input
The procedure is the same as described in the
previous paragraph, the capacitor C234 being
used to trim the rectangular wave-form.
Nastaveni frekvencni kompenzace vstupnich
delifiu
Odpojime kalibracni jednotku a na vstup Y1
(F201) pfivedeme obdślnikovś napgti 10 kHz.
Pfepinać S201 dame do p o lo h y --------; pfepinac
S203 do polohy 0. Velikost obrazu nastavime
na 3 dilky a udrźujeme ji po celou dobu na-
stavovśni. Po nastaveni zopakujeme stejny po­
stup na vstupu Y2 (F202), avsak S201 dame do
polohy 0 a S203 do polohy ±~z~r.

Adjustment of Input Divider Frequency
Compensation
Disconnect the calibrator and apply a rectan­
gular-wave voltage with a frequency of 10 kHz
to the Y1 input (F201). Set the switch S201 to
the position
“zrzrz"
and the switch S203 to the
position “0 “. Set the image size to 3 divisions
and keep this setting throughout the adjust­
ment procedure. Repeat the procedure for the
Y2 input (F 2 0 2 ) after having changed the
switch S201 to the position “0 “ and the switch
S203 to the position
“z r r z “.

Nastaveni vstupni kapacity
Na vstup „ Y l“ ( F201] pfivedeme pfes kali-
bra£ni jednotku obdelnikove napgti. Dostavime
obrśzek pomocnymi prvky tak, aby byl dosta-
tecnS jasny a ostry a velikost asi 3 dilky po
celou dobu nastavovdni. Dostavime optimślni
tvar obdelniku kondenzdtory v jednotlivych
rozsazich podle tabulky. Po dostaveni zopaku­
jeme postup na vstupu „Y2“.

Input Capacity Adjustment
Apply a rectangular-wave voltage to the “Y l “
input (F201) via a calibrator. Use the control
elements to adjust the image to be sufficiently
bright and sharp and keep the size of the
image about 3 divisions throughout the adjust­
ment procedure. Trim the shape of the rectan ­
gles to an optimum by means of the capacitors
as indicated in the table below for the indivi­
dual ranges. Repeat the procedure for the
“Y2“ input.

UDRŻBA HORIZONTALNiHO ZESILOVACE
Kontrola kalibrace citlivosti
Ovlddaci prvky nastavime takto:
Pfepinać S302 do polohy 20mV/dil; S301 do
polohy a S303 do polohy 0.
Potenciometr zmgny citlivosti R348 dśme do po­
lohy „KAL. X “.
Zapneme pristroj a dostavime ostatnimi prvky
obrśzek na stinitku tak, aby byl dostatecnS
jasny a ostry.
Potenciometrem R363 „Kalibrace citlivosti“ na-
stavime velikost obrśzku na stinitku tak, aby
velikost vstupniho napśti 60 mV odpovidala
vysce 3 dilkń.

Na vstup X I (F301) pfipojime napgti z generś-
toru obdślnikovśho napgti 10 kHz. Vstupni

MAINTENANCE OF HORIZONTAL AMPLIFIER
Calibration Sensitivity Check
Set the control elements as follows:
Switch S302 to the position 20 mV/div.; switch
S301 to the position
“zrzrz";
switch S303 to the
position “0 “; sensitivity adjustment potentio­
meter R348 to the position “X CAL.“.
Close the mains switch and use the other
control elements to adjust a sufficiently bright
and sharp image on the screen.
Using the potentiometer R363 “GAIN ADJ.“,
set the size of the image to make the voltage
of 60 mV correspond to 3 vertical divisions.
Frequency Compensation Adjustment
Apply a rectangular-wave voltage with a f r e ­
quency of 10 kHz obtained from a generator
to the X I input (F301). Set the input divider
