FIELD CALIBRATION
Field calibration allows simple calibration to be carried
out in the field without the use of additional test
equipment. Other calibration procedures require the use
of the GMI Manual Calibration software or the Workshop
System.
There are fundementals, in terms of instrument calibration,
that should be noted:
•
The gas should be of known traceable quality and
have total analysis.
•
The gas should be applied in the same manner as
the instrument is used, e.g. at a known pressure
which is constant and around, or slightly above,
normal atmospheric pressure.
•
The use of demand type regulators is not recom-
mended on instruments with Oxygen or Toxic cells
since these are affected by pressure pulses.
In Field Calibration Mode (FCM) the buttons perform
the functions indicated in CAL Mode or SPAN Mode as
shown in Figure B-1.
