6-20 SOLA II User Guide
Performing a high calibration can be achieved in two ways, depending on the
sample conditioning system installed.
The high calibration standard is normally contained in a pressurized cylinder.
The pneumatic output of the analyzer can be used to switch the
corresponding selection valve in the SCS, or the high calibration standard can
be manually introduced to the analyzer. Based on this, the Calibration Setup
menu offers two functions:
Calibrate High: Used when the analyzer is expected to switch the valves.
λ
Recalibrate High: Used when the calibration standard is introduced
λ
manually to the analyzer.
1. Go to Configuration > Calibration Setup > High Cal Value. Set the high

calibration value to match the concentration of the standard used.
2. Step down to the Average Cal Readings screen. It is recommended that
you set this value to the maximum (240).
3. Exit the Calibration Setup menu, and go to Configuration > Stream Setup
> Purge Time. Set this value. It should be long enough for the unit to
stabilize (time varies depending on the location of the switching valve in
the SCS and the flow rate of the sample). Exit this menu.
4. Go back to the Calibration Setup menu. Step down to the Calibrate High
screen, and press Enter to perform the calibration.
At this point, the analyzer will energize the calibration solenoid and start a
purge cycle. Once the purge cycle is completed, the detector reading will be
averaged for the programmed number of calibration readings (readings are
performed once a second). The resulting average will be latched to correspond
to the high calibration value concentration.
