Schneider Electric Pressure Transmitter IAP10S-F

Ensure required tools are available

Follow the required protocol to remove the device from online operation

Override the milliamp output to the High Failsafe setting

Confirm the mA output corresponds to the High Failsafe setting

Override the milliamp output to the Low Failsafe setting

Confirm the mA output corresponds to the Low Failsafe setting

Ensure the FoxCalTM feature is enabled before starting calibration

Is the input pressure accuracy at least four times better than the transmitter’s reference accuracy specification?

Perform calibration at LRV point

Perform calibration at URV point

Is the FoxCalTM feature disabled after URV calibration?

Rezero the transmitter output after stabilization at final operating temperature?

De-energize transmitters before removing threaded housing covers

Ensure no flammable or combustible atmosphere is present before disconnecting equipment

Turn off the transmitter power source

Disengage the cover lock screw by turning clockwise (if applicable)

Remove the covers from the field terminals and electronics compartments by rotating counterclockwise

Remove the digital display by rotating it counterclockwise (if applicable)

Loosen the two captive screws and remove the electronics module from the housing

Access the transmitter’s top level menu

Navigate to TST DSP and initiate test

Step through the five test patterns

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?

Check underrange output value (should extend beyond 4 mA).

Check overrange output value (should extend beyond 20 mA).

For DP transmitters, is the output returned to linear mode before zero check and back to square root mode after?
