Remove the housing cover opposite the field terminal side.

If you are disassembling a transmitter with a LCD display, loosen the two captive screws
that are visible on the right and left side of the meter display.
3.
Loosen the two captive screws that anchor the board to the housing. The electronics
board is electrostatically sensitive; observe handling precautions for static-sensitive
components. Use caution when removing the LCD as there is an electronic pin
connector that interfaces between the LCD and electronics board. The two screws
anchor the LCD display to the electronics board and the electronics board to the
housing.

Using the two captive screws, slowly pull the electronics board out of the housing. The
sensor module ribbon cable holds the electronics board to the housing. Disengage the
ribbon cable by pushing the connector release.
Remove the sensor module from the electronics housing

Important
To prevent damage to the sensor module ribbon cable, disconnect it from the electronics board
before you remove the sensor module from the electrical housing.
2.
Carefully tuck the cable connector completely inside of the internal black cap.
