In the set measuring range the output signal is between 4 and 20 mA (OU2 = I) or between
20 and 4 mA (OU2 = InEG). When pressure is outside the set measuring range, the output
signal is as follows:
•
System pressure above the measuring range:
—

•
System pressure below the measuring range:

Customer-specific calibration (sensor trim)
A customer specific calibration (sensor trim) corrects the pressure offset and pressure
range to match a pressure standard. This provides a slope correction to the transmitter's
current characterization curve. An accurate pressure standard is required for a full
calibration. For more information on performing a Sensor Trim, see
•
Sensor Trim is a two-point sensor calibration that applies two end-point pressures
(CP1, CP2) then linearizes the output between them. CP1 and CP2 must be within the
scaled measuring range. For more information, see
•
Zero trim is a single-point offset adjustment. It compensates for mounting position
effects and is most effective when performed with the transmitter installed in its final

Output signal > 20 mA if OU2 = I.
Output signal 4 to 3.8 mA if OU2 = InEG.
Output signal 4 to 3.8 mA if OU2 = I.
Output signal > 20 mA if OU2 = InEG.
