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
