Valve Board Assembly
Introduction
This procedure describes the process for re-attaching the valve board assembly into
the lower module.
NOTE:
The valve board and analog board are a matched set for the Hct and SC
circuits and must be calibrated when either is replaced. This also applies when
replacing the lower module or electronics module, which contains these boards.
Calibration is not required when these boards are only removed and put back into
the same analyzer. Refer to Chapter 7, Service Programs, for instructions on
performing this procedure.

NOTE:
Wear suitable protection gear during this procedure.
