In Auto-Calibration Mode
The system will run a second calibration cycle if the first
calibration result was outside the user specified tolerance. If
the second calibration result is still outside the specified
tolerance limits, the analyzer will continue to use the
previously stored calibration and will flash the "CHK CAL"
message in the Info section of the LCD screen.
The "CHK CAL" message can be cleared by resetting the fault
alarm under:
VIEW DATA AND ALARMS
Or by running a manual calibration.
Placing the Analyzer into
Service
Your analyzer is now ready for routine operation. To place the
analyzer into routine service, press the control panel RUN key.
The analyzer typically runs unattended, analyzing sample
streams and calibrating itself at regular intervals. All relevant
parameters were programmed at the factory based upon your
application. Consequently, the analyzer is fully prepared for
routine operation once you complete these startup
procedures.
A qualified and authorized user can change many of the
operating parameters through the password-protected
"Technician Level" menu as detailed in the USER INTERFACE
menu.
Validating a Calibration
Standard
You can check the analyzer's calibration accuracy at any time
using the validation function. Validation consists of running
a single measurement cycle and reporting the result in
concentration. This reported result can then be compared to
the expected value, which is the known concentration of the
validation solution, to determine the accuracy of system
calibration.
The advantage of using this function over the Run Analysis
function is that prior knowledge of the concentration allows
for validating the accuracy of the analyzer, without affecting
the data reporting to your control center or device.

REVIEW/RESET ALARMS
Running a validation is identical to
running an analysis: Although the results
are printed they are not stored, alarm
conditions are not tested, and the analog
outputs are not updated.
It is highly recommended to allow the
NOTES:
Orion 2210AM Ammonia Analyzer to
complete its measurement cycle rather
than using the STOP key. If the STOP key
is pressed before a measurement cycle is
complete, it is highly recommended to
perform both the AUTO PRIME ALL and
CLEAN sequences described in Startup
and Operation Section.
Running an Analysis
(Analyze Once)
Although the analyzer is usually set up to analyze sample
streams on a regular schedule, you may wish to execute an
analysis on command to obtain an immediate result. This
function allows you to run single or multiple analyses on a
sample without requiring that the automatic mode be initiated.
The analyzer then runs the specified number of analyses,
tests for alarm conditions, exercises the analog outputs, and
prints the results exactly as if it were in the automatic mode.
To run multiple analyses (more than one) set the number of
repeats in ANALYSIS menu:
