Calibration
The DP140 is factory-calibrated for installation on a
wall or other vertical surface, which requires no field
adjustment. If you mount the DP140 on a horizontal
surface, a slight zero shift may occur that depends on
the range of the sensor. Correct any zero or span shift
by software adjustment in the user’s control system. For
calibration, access both zero and span potentiometers
under the cover of the unit, on either side of the terminal
strip. See Figure 4.
Note: A trained individual must complete
calibrations with the correct equipment and
standards for the pressure range of the DP140.
