Prior to performing the following instructions it is essential, to be grounded according to established procedures. Failure to be properly grounded will result in damage to the EPROM Chip and void the warranty.

5.3.1.Turn off the analyzer power and disconnect the power cord.

5.3.2.Lift the analyzer cover and locate the PC electronics board, refer to Figure Six.

5.3.3.Depending on the type of chip holder in the analyzer, different techniques are required to replace the existing EPROM with the EPROM labeled 2.12CBI. Facing the analyzer’s front panel, locate the EPROM socket on the left side of the PC electronics board near the rear of the analyzer. If the chip socket has a metal lever at the top, it is a Zero Insertion Force Socket (Step 5.3.4). If the chip socket does not have a lever, it is a Low Profile Socket (step 5.3.5). Figure Six illustrates the low profile socket. Use the appropriate instruction to replace the chip.
