8510C Adjustments

Procedure 1. Vertical Alignment Adjustment (CRT)

The original 85101C display/processor incorporated a cathode ray tube (CRT). The current

design incorporates a liquid crystal display (LCD). This procedure applies only to

instruments that are equipped with a CRT.

NOTE The vertical alignment can be adversely affected by magnetic interference.

Before adjusting the vertical position, be sure the analyzer is in a

non-magnetic environment and the CRT is degaussed.

1. Switch on the system and allow it to warm up for 60 minutes.

2. To access the vertical position and focus controls, remove the side panel nearest the

display.

3. Insert a narrow, non-conductive, flat-head screwdriver ( 2 or more inches long) into the

vertical position hole.

4. Adjust the control until the softkey labels align with the softkeys.
