4.
With the rear of the instrument facing you, place the
fingers of both hands over the front edge of the front
subpanel. Then, using both thumbs, press forward gently on
the crt funnel near the front of the crt. When the crt base
pins disengage from the socket, remove the crt and crt
shield through the instrument front subpanel. Place the crt in
a safe place until it is ready to reinstall. If the plastic crt
corner pads fall out, save them for reinstallation.
To reinstall the crt, perform the following steps:
5.
Reinstall any plastic crt corner pads that may be out
of place. Insert the crt, crt shield, anode lead, and Trace
Rotation leads through the front-panel opening. Make sure
all pins are straight and that the indexing keys on the crt
base and socket are aligned. Make sure the crt shield
ground clip only makes contact with the outside of the crt
shield.
6.
Push the crt base into the socket. Check that they are
flush together as viewed from the rear and that the crt is
seated properly in its front-panel opening.
6a. If applicable, reinstall the shield at the back of the
crt; then secure it with two nuts (removed in step 3a).
7.
Reinstall the crt frame and light filter; then secure
them with two screws (removed in step 3).
8.
Reconnect the crt anode lead to the High-Voltage
Multiplier (disconnected in step 2).
9.
Reconnect the four deflection-plate wires and the
Trace Rotation connection (disconnected in step 1).
High-Voltage Shield
To remove the High-Voltage shield, perform the following
steps:
1.
Remove the screw from the plastic high-voltage cover
on the bottom section of the Main circuit board. Press gent
ly on the rear of the cover and slide it forward.
2.
Remove the screw securing the High-Voltage shield
to the Main circuit board (located at the bottom of the circuit
board near the right side of the frame).
3. Remove two screws securing the left rear of the High-
Voltage shield to the back of the chassis frame.
4. Remove the screw from the front upper right-hand
corner of the High-Voltage shield.
5.
Remove the screw at the front upper left-hand comer
and rotate the support bracket away from the High-Voltage
shield.
5a. For instruments equipped with the Preregulator
board (A18), remove the screw from the front of the High-
Voltage Shield at the upper-left hand comer.
6.
Lift the shield up and out of the chassis frame by re
moving the right rear comer first.
To reinstall the High-Voltage shield, perform the following
steps:
7.
Insert the shield into the chassis frame. Make sure
that the shield’s right and back top edges are in their chas
sis frame guides, that the crt socket-wire assembly is in its
cutout, and that the Alt Sweep board is in its plastic holder.
7a. If applicable, reinstall the screw to the front of the
High-Voltage Shield (removed in step 5a).
8.
Rotate the support bracket back into place and se
cure it with the screw removed in step 5.
9.
Reinstall the screw at the upper right-hand comer of
the shield (removed in step 4).
10.
Reinstall two screws securing the shield to the back
of the chassis frame (removed in step 3).
11.
Reinstall the screw holding the shield to the Main
circuit board at the right side of the frame (removed in step
2
).
12.
Reinstall the plastic high-voltage cover on the bot
tom of the Main circuit board and secure the shield and
cover with one screw (removed in step 1).
Attenuator/Sweep Circuit Board
To remove the Attenuator/Sweep circuit board, perform
the following steps:
1.
Use a 1 /16-inch Allen wrench to loosen the set screws
in the following knobs and remove the knobs: CH 1 and
CH 2
VOLTS/DIV Variable,
SEC/DIV Variable,
and
SEC/DIV. Note the position of the SEC/DIV knob for
reinstallation reference.
