Schneider Electric Pressure Transmitter IAP50S-F

Set up the calibration equipment as per transmitter instructions (see Calibration Setup, page 77)

Is zero pressure applied or equal pressures on both sides of a differential pressure transmitter?

Is the transmitter an absolute pressure transmitter with full vacuum applied?

Ensure the transmitter is stabilized at the final operating temperature.

Is the FoxCalTM feature enabled?

Apply pressure equal to or near the LRV and enter the pressure for the lower trim point.

Apply pressure equal to or near the URV and enter the pressure for the upper trim point.

Perform a single point calibration (zeroing) with a nonzero pressure input if desired.

Check if the underrange and overrange output values extend beyond 4 and 20 mA, respectively.

Perform zero adjustment after installation?

Rezero transmitter output at final operating temperature for high accuracy applications?

Rezero transmitter output to eliminate zero shifts from position effects?

Check underrange and overrange output values extend beyond 4 and 20 mA, respectively.

Ensure PV is in square root mode

Access PV Flow URV function from Device Setup > Full Configuration > Edit Parameters

Perform two-point calibration if FoxCalTM is enabled

Rezero the transmitter output after stabilization at final operating temperature

Check underrange and overrange output values to ensure they extend beyond 4 and 20 mA

Return output to linear mode for zero reading check (DP transmitters only)

Connect a digital voltmeter and precision resistor in the output loop

Ensure calibration equipment is set up as described in Calibration Setup, page 77

Check if the FoxCalTM feature is enabled

Rezero the transmitter output at final operating temperature for high accuracy applications
