4.3.2. Span Calibration Summary

Following is a simple, step-by-step procedure for executing a "full scale" span calibration of a 9016,
9021, or 9022 Intelligent Pressure Scanner. For Models 9021 and 9022, skip the steps that
manipulate valves, as denoted with a double asterisk (**). It is assumed that all channels in the unit
are of the same full scale pressure range. Optional commands are shown within brackets [ ].
Ensure that valves are in RUN/CAL mode (default).
... normal data acquisition
Perform Re-zero calibration
Place the module calibration manifolds into the CAL
position if this is the desired pressure application input.
The RUN position may be a better choice for modules
with transducers having different ranges.
Apply exact full scale pressure to appropriate module
CAL and CAL REF inputs [or optionally to RUN
inputs].
Delay for settling of pneumatic inputs
Verify that measured data reads near expected full scale
Instruct module to calculate new gain coefficients for all
16 channels
Place calibration manifold back into the RUN position
Store new gain coefficients to transducer non-volatile
memory
... continue normal data acquisition
