NOTE: The cell and characterization board are a matched set. If
performing this procedure to remove and install the same cell (for
instance, to change the O-rings or clean the cell), the characteriza-
tion board does not need replacing. If performing this procedure to
replace the cell with a new cell, replace the entire cell and character-
ization board assembly.
1. Remove the transmitter from the process.
2. Remove the left housing cover from the electronics housing

that secure the amplifier assembly to the electronics housing
(Fig. 8-1).

housing to unplug it from the characterization board connec-
tor (Fig. 8-1).
