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

 

[w0C01] for CAL

 

if this is the desired pressure application input. The RUN

 

 

 

 

 

position may be a better choice for modules with

 

[w0C00] for RUN

 

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

 

[rFFFF0]

 

 

 

 

 

Instruct module to calculate new gain coefficients for all 16

 

ZFFFF

 

channels

 

 

 

 

 

Place calibration manifold back into the RUN position

 

w0C00

 

 

 

 

 

Store new gain coefficients to transducer non-volatile

 

w09

 

memory

 

 

 

 

 

… continue normal data acquisition
