Problem: The unit does not display the proper pressure.
Remedy:
Check to see that the tubing is connected properly to the
#1 inlet port.
Remedy:
Make sure that the tubing does not have a kink or a sharp
bend.
Remedy:
Make sure that you are using the correct 3/16” ID tubing

paper is fed properly as described in Section 3: Loading the
