CALIBRATION MODE
The device must be calibrated every 30 days using the white tile and camera test target. The two parts are
combined in the calibration reference.
Refer to the Cleaning section in the Appendices for information on cleaning the calibration reference.
NOTE:
Make sure to use the calibration reference supplied with the device for calibrating. Do not substitute
this reference with a reference from another device. The serial number on the reference should match the
reference serial number displayed on the device calibration screen.
Calibration Notes
The
white tile and camera test target are severely affected by smudge marks, dust, and finger
prints
. Refer to Appendices for calibration reference cleaning procedures.
Do not move device while taking the calibration measurements
. If motion is detected by the contact
sensors, an error message will be displayed and calibration aborted.
Calibration Reference
The calibration reference is designed to keep the white tile and camera test target free of dust and debris. The
calibration reference is stored in the docking station and is separated into two parts when used.
