To remove the optional Barometric reference sensor, first turn off the CPC7000 and loosen the Phillips head screws that secure the
door. The barometric reference sensor is positioned behind the front door next to the primary transducer in the pressure controller

and lifting the barometric reference sensor out of the chassis.

9.1.4 Cleaning
Cleaning the CPC7000 outside housing has to be done only using a moistened cloth. The display/ touchscreen must be cleansed
using only a soft microfiber cloth with the power to the unit turned off in order to avoid accidental touchscreen responses.
CAUTION! Further access to the interior of the instrument is NOT recommended. There are no
user-cleanable components inside the chassis.
