Then return the V O LTS/D IV Variable control to the CAL
detent and finish the check.
5 . Check In p u t C oupling
a. Set both VOLTS/DIV switches to 50-mV.
b. Set the calibration generator to produce a 200-mV
standard-amplitude signal.
c. Position the bottom o f the signal on the center hori
zontal graticule line using the Channel 2 POSITION control.
d. Set the Channel 2 input coupling switch to AC.
e. CHECK—Display is centered about the center hori
zontal graticule line.
f. Set the VE R TIC A L MODE switch to CH 1 and move
the input signal from the CH 2 OR Y input connector to
the CH 1 OR X input connector.
g. Repeat parts c through e fo r Channel 1.
6. C heck A L T and C H O P O peration
a. Set:
V E R TIC A L MODE
BOTH-ALT
AC-GND-DC (both)
GND
SEC/DIV
10 ms
b. CHECK-Display alternates between the Channel 1
and Channel 2 displays. If necessary, use both POSITION
controls to separate the tw o traces.
c. Set VE R TIC A L MODE to CHOP.
d. CHECK—Channel 1 and Channel 2 displays are both
displayed simultaneously.
7 . Check V O L T S /D IV V a ria b le C o n tro l Trace
S h ift
a. Set:
SEC/DIV
0.2 ms
Adjustment Procedure—2213 Service
b. Center the trace on the center horizontal graticule
line using the Channel 1 POSITION control.
c. Rotate the CH 1 VO LTS /D IV Variable control
counterclockwise through its fu ll range.
d. CHECK—That the trace does not shift more than 2.5
divisions.
e. Return the CH 1 VO LTS /D IV Variable control to
its CAL detent.
f. Set the V E R TIC A L MODE switch to CH 2.
g. Repeat parts b through e fo r Channel 2.
8 . A d ju st In v e rt Balance (R 2 6 4 )
a. Set the CH 2 VO LTS /D IV switch to 20 mV.
b. Center the trace on the center horizontal graticule
line using the Channel 2 POSITION control.
c. Push in the IN VER T button.
d. ADJUST—Invert Bal (R264) to position the trace
on the center horizontal graticule line.
e. Return the INVERT button to Normal (button out).
f. Repeat parts c through e u ntil there is no trace shift
when switching the INVERT button between Invert and
Normal.
9. A d ju st Trigger Balance (R 1 5 4 )
a. Set the I NT switch to CH 2.
b. Connect the digital voltmeter low lead to chassis
ground (TP501) and the volts lead to pin 16 o f U421; note
the voltage reading fo r use in part d.
c. Set the I NT switch to CH 1.
d. ADJUST—Ch 1/Ch 2 Balance (R154) so that the
voltage reading is the same as that obtained in part b.
