Measurement Settings, from Device, select i1 Pro and connect the device to your computer. The dialog shows parameters to set for the measurement.
INFO: Support for X-Rite
|
- Make your selection for Illuminant.
- Make your selection for Observer.
- Select the mode Spot/Scan, with or without UV filter (requires device calibration). The Spot mode allows scan count 1. More than 1 will switch to Scan mode and vice versa.
- Enable or disable Zebra Ruler support for spectrophotometer X-rite i1 Pro2. Note, for device X-rite i1 Pro this option is disabled.
- Use Average to render your measurements.
Device Calibration
Before starting to use the device, it must be calibrated. Place the device on its white reference calibration plate and click on Calibrate button to make the action.
The device is equipped with device light indicators on its top housing, that provides feedback on the status of the device. (off) The device is either not connected to your computer. (solid white) The device is connected but needs calibration. (pulsating white) The device is connected and ready for measurement. (solid red) The calibration of the device failed due to a hardware problem. To avoid interference of the device status indicators with the measurement process, the device status indicators are switched off during the measurement.
When the connection with the device and calibration is done correctly, a dialog will pop up. When the connection with the device and calibration is not done correctly, proceed to repeat the connection and calibration, until the calibration succeeds.
After the calibration, you can see when the calibration will expire and must be renewed. 
The option "Check Device Stability when Calibrating" is verifying the white reference of the device and its stability. When the calibration succeeded, the response tells you the delta E of the device white reference which should not go beyond delta E 0.15.
Spot Measurement
1) Make sure that your device is calibrated and the status indicators are pulsating white.
2) Select Spot Mode.
3) Position the device on the patch you would like to measure.
4) Press the measurement button on the device. Status indicator lights switch off during measurement and pulsate green once the measurement has been successfully finished.
Scan Measurement
1) Make sure that your device is calibrated and the status indicators are pulsating white.
2) Select Scan Mode.
3) Enter scan count (number of the patches to measure).
4) Position the ruler with the device on the media in front of row #1 of your chart. It does not matter if you scan the row from left to right or right to left.
5) Press the measurement button on the device and wait one second before you start moving the device to the opposite side of the ruler. Hold the measurement button pressed until you have reached the far end of your test chart.
If you release the button before you reached the measurement of the full line, repeat from the beginning.
The status indicators on the device provide feedback if the measurement was successful: (2x green flash) the row was measured successfully. (2x red flash) the row was not measured successfully because not all patches could be recognized. Measure the row again, but reduce your measurement speed and make sure that the device starts and ends the measurement before and after the patches of the chart. (4x red flash) the row was not measured successfully because you started reading the patches too early without giving the tungsten filament lamp enough time to warm up. Measure the row again but allow the lamp time to heat up before you start moving the i1Pro device.
6) Position the ruler with the device in front of the next row of your test chart and measure the next row.
