Keithley 2000 Repair Manual

Front panel disassembly
Use the following procedures to remove the display board and/or the pushbutton switch pad:
NOTE You must first remove the case cover, the front/rear input switch, and the front input
terminal wires as described in earlier in this section.

2. Remove the front panel assembly.
This assembly has four retaining clips that snap onto the chassis over four pem nut studs.
Two retaining clips are located on each side of the front panel. Pull the retaining clips
outward and, at the same time, pull the front panel assembly forward until it separates
from the chassis.
3. Using a thin-bladed screw driver, pry the plastic PC board stop (located at the bottom of
the display board) until the bar separates from the casing. Pull the display board from the
front panel.
4. Remove the switch pad by pulling it from the front panel.
