NIRS™ DA1650
User Manual 6008 1286 / Rev. 8 4:27
The sample inside the check sample cell may have changed over time and the proper
action would then be to either replace the sample and/or to run a new check sample
definition to re-define the target values or even review the limits in FossManager.
If the check sample is deemed to be OK and fresh then running the
Instrument
Diagnostics (from Care view) may give you an indication if something has changed
inside the instrument. Should the Instrument Diagnostics fail, then our
recommendation is to contact your local FOSS representative for assistance.
Note: When not in use the check sample should be kept in a clean
and dry location.
4.4.2 FOSS Check Sample
This refers to the artificial FOSS check sample. For info about the empty check
sample cell please see section 4.4.1 Check Sample.
The FOSS check sample supplied with NIRS DS2500 and NIRS DA1650 is an
artificial type check sample intended for regular control of instrument stability. The
frequency for running the check sample is determined by your local quality routines
but the normal recommendation is to run daily check sample controls.
Running the check sample is done in ISIscan Nova just like you run a normal sample.
The check sample requires a check sample product to be set up in FossManager with
a proper operation profile and check sample prediction model.
The check sample equation is delivered on a USB key together with the check
sample. This equation will predict a specific distance in the check sample spectra and
the results is presented as a number without units. The result is compared to the limits
that have been set for the check sample product and a Warning (yellow) or Error (red)
will be displayed if the result is outside warning/action limits.
Setting up the Check Sample product (FossManager)
Before running the check sample you must create a check sample Product in
FossManager.
1. Import the check sample prediction model from the USB coming with the check
sample. The USB contains one prediction model for NIRS DS2500 and one
prediction model for NIRS DA1650. During import of the prediction model you
can create a new Parameter profile called "Distance" and link this to the model.
2. Create an Operation profile with Cup Type = "Check sample (FOSS)" and name
it e.g. "Check Sample FOSS".
