4.6Line 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.
