Calibration and Self-Test

This page is used for calibration of the internal pressure transducer
sensor and testing operation of hardware circuitry. Calibration is only
required for highly accurate measurement needs such as those needed to
comply with federally mandated regulations. Calibration should only be
performed by qualified personnel.
1.Select Primary or Secondary room. When selected, the gray box to the
right will indicate if the calibration will be applied to the on-board sensor
or the external sensor (Analog Ch1 or Analog Ch2). The indicated pres-
sure is shown.
2.Calibration of the on-board sensor requires that the faceplate be re-
moved and the captive screw holding the display cover must be loosened
(at the bottom-center of the display bracket).
3.Lift the cover to expose the clear and red tubing connecting the on-
board sensor to the pressure fittings in the rear of the unit.
4. Remove the Tubing
