long beep sound, and the pressure will be indicated as “0.00”.
<Connecting Pressure Tube>
Connect the pressure tube to the (+) or (-) port.
Connect the other end of the tube to the port (e.g. duct) where the pressure is to be measured.

In order to make an accurate measurement, make
sure that the tube does not have any holes, which
could cause air leakage. Also if the tube is bent, the
