Schneider Electric Pressure Transmitter IAP10S-T

Connect a digital voltmeter and precision resistor in the output loop.

Is the calibration equipment set up as described in the Calibration Setup, page 77?

Perform trim calibration at the following mA outputs

Is the FoxCalTM feature enabled?

Was the transmitter rezeroed after stabilization at the final operating temperature?

Were zero shifts resulting from position effects eliminated by rezeroing the transmitter output?

View the total days the transmitter has been in service using the 1 Device Setup > 2 Calibration > Time in Service Meter menu selection.

View the user days since the last reset using the 1 Device Setup > 2 Calibration > Reset User Days menu selection.

Reset the user days to zero if necessary.

Perform a two-point calibration if FoxCalTM is enabled.

Rezero the transmitter output once it has stabilized at the final operating temperature.

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

Ensure the transmitter is in linear mode for DP transmitters

Disable FoxCalTM if performing a two-point calibration

Confirm LRV and URV values are within the calibrated range

Apply minimum pressure and record LRV

Access the transmitter’s top level menu

Navigate to TST DSP and initiate test

Step through the five test patterns

Navigate to Device Setup > Full Configuration > View Parameters or Edit Parameters

Check underrange and overrange output values extend beyond 4 and 20 mA

For DP transmitters, ensure zero reading is checked in linear mode before returning to square root mode

Display LRV and URV in pressure units using RERANGE function

Ensure LRV and URV are within calibrated range if FoxCalTM is disabled
