4.3.2. Span Calibration Summary
Following is a simple, step-by-step procedure for executing a “full scale” span calibration of a
9116 Intelligent Pressure Scanner. It is assumed that all channels in the unit are of the same full
scale pressure range. Optional commands are shown within brackets [ ].
Description Model 9116 Command
Ensure that valves are in RUN/CAL mode (default) [w1200]
… normal data acquisition
Perform Re-zero calibration See Section 4.2.2
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.
[w0C01] for CAL
[w0C00] for RUN
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 [rFFFF0]
Instruct module to calculate new gain coefficients for all 16
channels
ZFFFF
Place calibration manifold back into the RUN position w0C00
Store new gain coefficients to transducer non-volatile
memory
w09
… continue normal data acquisition
