Calibrating Multiple Analyzers in One Calibration Session
When using gas blends for auto calibration of multiple
analyzers, the Model
2010D
has the capability to calculate span
concentrations for each gas in the blend. For example, three
instruments may be calibrated simultaneously with a gas blend
containing SO2, NO, and CO. One of these gases must be assigned
as the "primary gas" when the sequence is set up; the other two
will be considered secondary gases. The
2010D
will automatically
calculate the concentrations of all gases in a multi-blend gas
standard and present them in the status screen. The
concentrations assigned to the primary gas for each sequence
point will determine the concentrations of the secondary gases,
which are calculated from the dilution ratio needed to produce
the primary gas and the relative concentrations of the secondary
gases in the gas standard.
Performing Manual Calibrations
The Model
2010D
may be used to perform instrument calibrations
manually by accessing the programmed calibration sequences. The
programmed sequences are found under the main menu area
identified as Sequences.
The Run item in the Sequences menu
allows manual calibrations to be invoked by two methods:
Operator Stepped and Timer Stepped.
Calibration sequences and Diluent and Source Gases must be
defined before performing manual calibrations. Refer to Section
6, "Model
2010D
Calibration Set-up", for more information.
Each method of performing manual calibrations is described in
the subsections that follow.
