The SpectroJet has a scanning window that is two patches wider than the actual measuring area:
To scan the above Color bar, follow the instructions below :
Press the green measuring button shortly to start scanning. A short beep will sound when the last patch is registered.
If you need to scan a multi-row bar repeat this until all bars are done.
It is possible to have the SpectroJet scanning two measurement conditions: For instance density measurements with a polarization filter and spectral color without. In this scan left-to-right until the beep, and (without touching the green button) scan back (right-to-left) until a second beep sounds.
