NOTE:
In this section the word
Calibration means to match the Instrument to the input device, so
that a specific signal from the input device is equated to a specific pressure and no other, (to
the capabilities of its input resolution).
Apply power to the cabinet and allow the system to stabilize for about 30 minutes. Allow the
transducer or other input device to come up to operating conditions.
