6-24 Replacing Clear Plastic LCD Protector – 3-61368
This procedure is written with the assumption that the Main PCB Assembly has been removed from the
instrument as described previously, and that the Clear Plastic LCD Protector must be replaced. The
replacement procedure is the same for MS2026C, MS2027C, and MS2028C instruments.
Part Numbers
• 3-61368 – Clear Plastic LCD Protector. For MS2026C, MS2027C or MS2028C instruments
Procedure
1. Open the instrument case and remove the Main PCB Assembly.
Refer to Section 6-21 “Removing MS202xC Main PCB Assembly” on page 6-44.
2. If the LCD Display is to be replaced, then remove the LCD Display as described in
Section 6-23 “Replacing LCD Display – 3-15-154” on page 6-50. If the LCD Display is NOT to be
replaced, then skip to the next step.
3. Remove the Clear Plastic LCD Protector by pushing it from the front.
4. The protector has an inset edge which goes into the hole and faces out. The protector “lip” is set towards
the inside of the case.
5. The outside of the Protector has a protective “skin” that should be left in place until the instrument is
reassembled.
6. Clean the inside of the Protector by using compressed air and LCD compatible wipes.
7. Avoiding fingerprints, install the protector into the Case Front opening with the protector “lip” towards
the inside of the case.
8. If no further unit replacements are required, then install the LCD Display (if required) and install the
Main PCB and reassemble the instrument by using the following procedures:
• Section 6-23 “Replacing LCD Display – 3-15-154” on page 6-50 (if required)
• Section 6-25 “Installing Main PCB and Reassembling Instrument” on page 6-52
