Calibration Checks of Pressure Measuring Devices
Prior to initial field testing, each pressure transducer requires a 3 point calibration check with a
precision manometer or a NIST traceable pressure source within a year of its most recent certification.
1) Disconnect the P1 and P2 lines from the console.
2) Press Reset to Zero.
3) Connect the pressure measuring device with pressure generator to P1 Port.
4) Vent all ports. Let devices settle. Record values for ZERO (50% of full range). Value must be
/- 0.03” H

O of ZERO. If reading FAILS, consult Transducer Calibration section of this manual
to recalibrate transducer.
5-10) If reading PASSES, Conduct calibration checks at -4.5, -3, -1.5, 1.5, 3, and 4.5” H
