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.
