Routine Functions
Instrument Calibration
The instrument must be calibrated regularly to ensure the measurement data is accurate. If the calibration
interval has expired, you will not be able to make a measurement. The measurement is started from the
button on the right side of the instrument.
NOTE
If you used the Datacolor PAINT program to calibrate the instrument while it is attached to the
computer, you may be required to recalibrate it in stand-alone mode to update the calibration data
stored on the unit.
To calibrate the instrument:
1. Turn on the instrument.
2. Using the black button, navigate to the
calibration
icon on the live bar and select it:
3. The program will prompt you to measure the black
trap. Position the trap over the aperture and press
the
Measure
button.
When the black trap measurement is complete the
instrument will beep, and the program will prompt
you to measure the white tile.
4. Place the white tile over the aperture and
press the
Measure
button.
The instrument will beep when the measurement is completed, and
the program will notify you that the calibration is successful.
