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 [ ].
Description 9016 Command 9021/9022
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] [r0FFF0]
Instruct module to calculate new gain coefficients for all
16 channels ZFFFF Z0FFF
Place calibration manifold back into the RUN position w0C00 **
Store new gain coefficients to transducer non-volatile
