6.2.4 Getting access to Top Side of PCA
During disassembly, take careful notice of the position of isolation foils in so that you are
able to install them in their original position. This is very important for the Analyzer’s
safety. To get access to the top side, remove the upper plate (Shielding Lid): remove 4
pcs. M3 screws (total length of 6 mm). Refer to figure 6-2.
6.2.5 Getting access to Bottom Side of PCA
Important: to avoid contaminating the flex cable contacts with grease from your fingers,

cause immediate instrument faillure. Faillures typically show up when contaminated
instruments are operated in humid areas. Refer to figure 6-3.
