Access the span calibration screen as described in the Local Operation section of this
manual.

Set a known pressure to the pressure port of the sensor to be calibrated equal to, or
near, the upper end of the range of the instrument. The applied pressure must be great-
er than 50% of the span or span adjustments will not be accepted. Adjust the measured
pressure on the span calibration screen to match the true applied pressure. Press the
