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.
