4.3.4 Instrument Calibration
Instrument Calibration of NIRS DA1650 is a task normally carried out by a FOSS
representative at the time of installation and/or at service or Preventive Maintenance
visits. NIRS DA1650 is using DDA technology (diode array) which is very stable
over time and insensitive against e.g. vibrations. The instrument calibration
performed prior to delivery or at installation will therefore last a long time.
The required ERC and EWC tools for carrying out instrument calibration of NIRS
DA1650 are therefore not included with the instrument. They can be purchased from
FOSS for any customer wanting to do their own instrument calibrations.
Instrument Calibration in NIRS DA1650 is found in the Care menu and it includes
two functions:
• Intensity Correction, using the ERC tool (external reference correction)
• Instrument Calibration using the EWC tool (external wavelength calibration)
Note: For instrument calibration it is important that the
instrument is thoroughly warmed up and that is carried out in a
stable environment. Recommendation is that the instrument
should have been turned on for at least 2 hours before
calibration.
USB KEY
With the ERC and EWC cups comes a matching USB key containing the calibration
file for the specific cup. The file and the cup are matched by a serial number
programmed into the RFID on the EWC/ERC cup. These EWC/ERC keys must be
connected to the instrument when requested by the software.
