CALIBRATING
The software application prompts for an instrument calibration when required. The frequency at
which this occurs depends on the application. Refer below for procedure.
The calibration reference consists of a ceramic disk for white calibration measurements, and a
trap opening for black calibration measurements. The instrument shoe fits snuggly in both
positions.
Refer to Cleaning section in the Appendices for information on cleaning the optics area and
references.
NOTE:
Make sure to use the calibration reference supplied with the instrument for calibrating.
Do not substitute this reference with a reference from another instrument. The serial number
on the reference should match the reference (plaque) serial number on the instrument.
Calibration Notes
•
Dirt or dust in the aperture area will cause an inaccurate calibration reading. Refer to the
Appendices for optics cleaning procedure.
•
The white ceramic plaque in the calibration reference is dramatically affected by
smudge marks, dust, and finger prints. Refer to Appendices for calibration reference
cleaning procedures.
•
The black trap should be cleaned periodically to remove any dust or
contamination. Refer to Appendices for black trap cleaning procedures.
•
Do not release the instrument while taking a calibration measurement. If the
instrument is released, calibration will be aborted.
Calibration Procedure
1.
When a calibration is prompted for by the application, select the appropriate option to initiate
the calibration.
2.
Remove the protective cap from the white ceramic plaque in the calibration reference.
3.
Position the instrument’s target window over the white ceramic plaque.
