7.4 PAH validation/calibration

Validation is a part of the normal maintenance of the PAH module and

is used to ensure the PAH module is functioning correctly. Calibration is

used to correct PAH reading offsets. Figure 7.9 is a flow chart showing the

procedures that must be done to ensure the PAH module is functioning

correctly.
