Introduction to Initializing Calibration Sequences
Calibration sequences are templates that are used for defining
calibrations. Each sequence is composed of up to 20 calibration
points, each point representing a concentration of a calibration
gas. Sequences may be controlled externally, internally or may
be used when performing manual calibrations. The calibration
sequences are stored in non-volatile memory for usage at a later
time.
The Model
2010D
supports four types of calibration
sequences. These sequences are:
Gas Dilution
A metered quantity of source gas is
diluted with a metered quantity of
diluent. Note: The source gas could
be from a multiple blend cylinder.
Ozone
A metered quantity of diluent is
irradiated by a precisely controlled
ultraviolet lamp in order to produce
ozone.
Gas Phase Titration
A metered quantity of source gas is
diluted with a metered quantity of
ozonated diluent.
Permeation
A metered quantity of permeation source
gas is diluted with a metered quantity
of diluent.
Multi-Gas Sequence
Each point of a Multi-Gas Sequence may
be of a different type and use a
different source gas.
The first four sequence types may be used when all points in the
sequence represent the same type and the same source gas. The
Multi-Gas Sequence, though more difficult to set up than the
other types, provides the most flexibility, allowing the Gas
Standard, gas component, source MFC and Instrument Solenoids to
be independently selected for each point. This allows multiple
types of calibrations to be performed from within the same
sequence.
