Following is a simple, step-by-step procedure for executing a specified-value span calibration of

a Model 9116 Intelligent Pressure Scanner. For the purposes of this example, it will be assumed

that an upscale pressure of 14.9800 psi is available from a dead weight tester for the calibration

of 15 psi internal transducers. All sixteen channels are 15 psi full scale.

Description

Model 9116 Command

Ensure that valves are in RUN/CAL mode (default)

[w1200]

… normal data acquisition

Perform Re-zero calibration first

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

With a deadweight tester, apply 14.9800psi to the

appropriate module CAL and CAL REF inputs [or optionally

to RUN inputs]

Delay for settling of pneumatic inputs

Verify measured data reads near expected full scale

[rFFFF0]

Instruct module to calculate new gain coefficients for all 16

channels

ZFFFF 14.98

Place calibration manifold back into the RUN position

w0C00

Store new gain coefficients to transducer non-volatile

memory
