CALIBRATION MODE
The calibration consists of a ceramic plaque for white measurements and a trap opening for black
measurements.
A calibration should be performed when prompted for by the instrument or when desired.
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 move instrument while taking a calibration measurement
. If motion is
detected, calibration will be aborted.
•
Important:
If the lamp signal in your instrument reaches a level that is
50% below the factory level stored, the warning symbol shown at the right
appears after a calibration is completed. This indicates that the illumination
level is getting low and you should have your instrument serviced soon.
White and Black Calibration
Procedure
1.
From the Main screen, use the
Navigation
control to move the highlight square to the
Calibration icon.
2.
Tap the
Select
control to access the calibration screen.
Calibration Required appears if calibration is needed. If calibration is not currently needed, the
time remaining before the next calibration along with the white reference (plaque) serial
number appears. To exit calibration mode without calibrating, select the Exit icon (
x
) in the
Progress column.
