Calibration
Page 93
Regulations generally require that the instrument be span calibrated against a certified calibration
source any time:
The instrument is moved.
The instrument is serviced.
The instrument’s units are changed by the user between volumetric and gravimetric.
Whenever the instrument characteristics may have changed.
Regulatory agencies establish the time intervals at which the instrument must be calibrated to
ensure satisfactory data for their purposes.
5.2
Pressure Calibration
The pressure sensors are a vital component of the instrument operation and the pressure calibration
should be checked on installation or whenever maintenance is performed.
A thorough leak check must be performed prior to performing a pressure calibration (refer to Section
6.3.5).
The pressure calibration can either be a two point calibration (one point under vacuum and another
point at ambient pressure) or a single ambient point calibration when very minor adjustments are
required.
Note:
Ensure that the instrument has been running for at least one hour before any calibration is
performed to ensure the instrument’s stability. When performing a two point pressure calibration, it
is advisable to perform the vacuum pressure calibration first.
5.2.1
Full Pressure Calibration
This section outlines how to perform a full pressure calibration. Using the required equipment follow
the steps below to complete a full pressure calibration.
Note:
This procedure is for firmware version 3.17.0007 and above. Ensure that the instrument has
been running for at least one hour before the calibration is performed.
Note:
Ensure units of measure are the same on both the barometer and instrument.
Equipment Required
