Calibration
When your instrument is first turned on, you should perform a calibration. Thereafter, a calibration
is required every hour or if a 5 °C temperature change has occurred. Calibration of the instrument
ensures optimum colour matching performance.
1.
Move the white reference slider to the closed/calibration position over the optics.
2.
Power on the instrument, then
go the “Calibration” menu (left button – down button until
cursor is on “Calibration” – confirm with MEAS/ENTER). The display will show the
following:
3.
Us
e the arrow keys to select “StandWhite” and press MEAS to initiate the calibration.
4.
Open the optics and align the measuring aperture in the air without aligning it directly
with a light source
. Go to the “Calibration” menu and select “StandZero”. Then press
the MEAS key to carry out the calibration.
5.
If the calibration was successful,
StandWhite“ or „StandZero“ will be ticked. If not, there
will be an “X” instead.
6.
Make sure to always reposition the slider back to
“Measure” location (optics opened)
before making a measurement.
Note:
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.
