Schneider Electric Pressure Transmitter IDP05S-F

Is the FoxCalTM feature enabled?

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

Perform a two-point calibration if FoxCalTM is enabled.

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

Is the transmitter operating in square root mode?

Return the output to linear mode for zero reading check.

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

Turn the cover lock screw clockwise to disengage the lock (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

Ensure 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 and URV points

Disable FoxCalTM feature if performing two-point calibration

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, respectively

For DP transmitters, return output to linear mode before zero check and back to square root mode after

Remove the device from online operation

Perform a minimum two-point sensor calibration check at the 4 to 20 mA lower and upper range points

Verify that the milliamp output corresponds to the applied pressure within the safety accuracy using the reference milliamp meter

Trim the calibration if necessary to match the calibration points

Return the device to normal operation

Document the test results per the requirements of the application

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 output rezeroed after stabilization at the final operating temperature?

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