Disassembly procedures

Case cover removal

Before removing the case cover, disconnect the line cord and any test leads from the
instrument.
To remove the handle, mounting ears, rear bezel, bottom screws, and cover:
1. Swing the handle below the bottom surface of the case and back until the orientation arrows on
the handles line up with the orientation arrows on the mounting ears. Pull the ends of the handle
away from the case.
2. Remove the screw that secures each mounting ear, then pull down and out on each mounting ear
to remove.
When re-installing the mounting ears, be sure to mount the right ear to the right side of the chassis
and the left ear to the left side of the chassis. Each ear is marked RIGHT or LEFT on its inside
surface.
3. Loosen the two captive screws that secure the rear bezel to the chassis, then pull the bezel away
from the case.
4. Remove the four bottom screws that secure the case to the chassis.
5. Grasp the front bezel of the instrument and slide the chassis forward.
6. Slide the chassis out of the metal case.
