Techkon

The measurement device does not need a special ruler. Ensure that the measurement surface is flat and eventually make the wedge shorter (load smaller media in the Proofer TP).
There will always be an ID strip printed. It is necessary to measure the ID strip first. QMS will identify the job and wedge (dimensions) for calibration, profiling, and other purposes.
To measure a Strip: 
1 Connect measurement device via USB and select the device in QMS.
2 Position the measurement head on top of the first patch.
3 Push and hold the green button.
4 Wait till the Speedometer appears and move slowly across the wedge to the end (last patch).
5 Release the green button and wait for the measured results.
