cylinder. For example, the nominal value for CO may be 20%, but your cylinder may actually have 19.96%
CO. 19.96 is the value that should be entered as a Target.
After the gas values have been entered, proceed with the calibration in the same manner as with the zero
calibration. Never perform a span calibration without first doing a zero calibration.
Automatic Sampling Parameters
This instrument is capable of communicating directly with a control instrument. This is valuable because
it will provide real-time entry of the temperature and millivolt information from the probe, allowing for an
accurate comparison between the IR % Carbon and the Probe %Carbon. To establish this
communications link, see “Communications and Source Setup – Atmosphere/ Temp Sources.”
The Automatic Sampling Parameters screen will allow the user to adjust the way that the MGA 6010
updates the COF / PF in the atmosphere controller. All of the parameters on this page can be
disregarded if the “COF/PF Adjustment Mode” is set to Monitor mode. These parameters only apply when
the instrument is in Control mode.
COF/PF Adjustment Increment
When adjustments are made automatically, this value indicates the size of the step that is made when the
COF/PF is changed. It is recommended that this number remain low to avoid making sudden changes to
the process that could be caused by temporary conditions.
COF/PF Adjustment Interval (minutes)
This indicates the frequency that automatic adjustments are made. We recommend making small
changes at a frequent interval instead of making large changes at longer intervals. This will prevent
temporary changes in atmosphere from making dramatic adjustments to the COF/PF.
