EXISTING BAROMETER
To assemble the existing PTB220 digital barometer and the wooden
case follow the instructions below.

by loosening its screws. Then the cover can easily be detached after the
barometer is installed into the case.

the case.
2. Unscrew the base plate.
3. Attach the PTB220 onto the base with
four M6x16 screws.
4. Thread the flat cable between the
battery covering and the base plate.
Connect the cable to D-terminal.
5. Remove the original 1/8" pressure
fitting of the barometer. Then, attach
the pressure tubing connector to the
PTB220. It is recommended to use
Loctite 572 joint paste for sealing.

frame. Check that the flat cable and
the pressure tubing come out of the
back opening.
