10.4 Setup

The following illustration for calibration setup shows a typical setup for either local or

remote calibration for an absolute or gauge pressure instrument. The ‘Optional Com-

puter’ is required only for performing a remote calibration.

The ‘Pressure Standard’ is normally a deadweight test instrument, and the ‘Volume

Controller’ refers to a hand operated variable-volume pressure vernier device. A dia-

phragm type vacuum gauge is recommended over the gauge tube type of vacuum

sensor for calibrating sub-atmospheric pressures. A vacuum source with the capacity to

generate 600 millitorr is recommended.
