Calibration
IMPORTANT: The calibration reference is dramatically affected by smudge marks and dust, and must
be kept clean. It is recommended that the instrument is cleaned regularly. Refer to the Cleaning
section later in this manual for procedure on cleaning the calibration reference and optics.
When your instrument is first turned on, you are asked to perform a calibration. Thereafter, a
calibration is required every 30 minutes or if a 3°C temperature change has occurred. Calibration of the
instrument ensures optimum sample measurement performance. If desired, a calibration can be
manually initiated by selecting Calibrate from the Settings menu.
The instrument includes an integrated white reference slider that protects the white reference when
not in use.
1. When displayed to do so, move the white reference slider to the closed/calibration position
over the optics.
2. Press Measure to initiate the calibration when the reference slider is positioned. A progress
bar appears at the bottom of the display to indicate the calibration status.
3. After a successful calibration, you are prompted to reposition the slider back to its storage
location before measuring samples.
Note: An error will be displayed if the white reference slider was not in the correct position for
calibration. If this occurs, close the slider and repeat the calibration process. After recalibration
this message continues, refer to Troubleshooting in the Appendices.
If at any time the instrument requests “Repeat Calibration” this is due to exceeding the current
temperature variation tolerance. Please recalibrate by initiating from the Settings menu.
