Schneider Electric Pressure Transmitter IDP05S-V

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

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

Zero Reading Check (DP Transmitters Only)

Return the output to linear mode for zero reading check.

Return the transmitter output to square root mode after zero check is complete.

Transmitters with the Optional Display

Unlatch the external zero button by turning it 90 degrees counterclockwise

Check for possible messages on the display

Relatch the external zero button by turning it 90 degrees clockwise

Set or Reset Using the Optional Display

Apply zero pressure to the transmitter or use a bypass valve to equalize pressure

Press the external zero button until the display reads CAL AT0, then release

Wait for the display to read AT0done to complete calibration

Apply the lower range value (LRV) pressure to the transmitter

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 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

Ensure the transmitter is not write protected

Disable FoxCalTM if performing a two-point calibration

Ensure the transmitter is in normal operating mode

Press the NEXT button until the display reads CALIB

Press the ENTER button to select CALIB
