Front Panel Disassembly Instructions
Instructions Visual
IMPORTANT NOTE:
• The front panel assembly should only be 
repaired in a clean and dust-free 
environment. 
• Failure to do so may introduce 
contamination between the EMI shielded 
window and the display.
• Also note that it may not be necessary to 
completely disassemble the front panel in 
order to repair or replace some of its parts. 
As such, this procedure should be tailored to 
suit the specific repair requirements.
Step 1:
• Carefully lift and remove the calibrator plug 
[This step does not apply to units with 
rear-panel connectors]
• This step is only applicable for calibrator 
assembly with the calibrator plug.
• For more information on the improved 
calibrator assembly, refer to “Improved 
calibrator assembly” on page 78.
