Calibration
All pressure ranges are factory calibrated and no calibration is necessary. You may adjust the zero
point if desired when changing ranges for example.
1. Allow the product to warm-up for 10 minutes (one hour is best) before you make a zero
adjustment.
2. With both ports open to the ambient pressure, press and hold the auto-zero button for at
least three seconds.
3. Release the auto-zero button after at least three seconds and the device will calculate and
store the new zero point.
Specifications
TIP
Generally, we do not recommended that the span calibration be performed in
the field unless a high quality calibrator with low differential pressure ranges is
available and the temperature of the sensor can be maintained. Contact the
factory for information on this type of calibration.
