Alternately, they may be verified and stored on the host computer’s secondary storage, and
later restored (if necessary) with the Download Internal Coefficients (‘v’) command (same
array/coefficient indexes as ‘u’).
4.6 Line Pressure Precautions
When operating Model 9116 pressure scanners at elevated line or reference pressures, care
must be taken when any command is issued that may result in shifting of the calibration valve.
The user must ensure that any valve shifts will not result in the internal DH200 transducers
being exposed to pressure transients that may exceed the proof pressure rating of the
transducer. This is especially important when operating at elevated reference pressures as a
shift to the CAL position may result in a rapid pressure change if the CAL/CAL REF pressure
varies greatly from the measurement reference pressure.
