5. Using the manometer, measure the actual differential pressure at the selected flow
rate. Compare the differential pressure to the differential pressure shown on the
Calibration Report.
NOTE: Typically, a 0.5”wc deviation equates to 5% flow error.
6. If the actual differential pressure is within acceptable limits (±4% of the full scale value),
no action is necessary. If the actual differential pressure is not within acceptable limits,
adjust the zero/span potentiometers inside the differential pressure transducer. The
pressure transducer is located inside the black enclosure on top of the unit.
