You can suspend measurement at many points in the measurement process. For automated devices, you can suspend measurement before any page measurement. For the X-Rite i1 Pro, you can suspend measurement prior to scanning any row of patches. 

• To suspend measurement, click Suspend. The suspended measurement data set will not appear in the Measurements tab of WorkFlow Editions, since it is incomplete. If you close ColorFlow, your suspended measurement is retained. 

• While you are measuring, all measurement data and information are automatically saved. If a system or power failure causes ColorFlow to quit unexpectedly, your measurements are retained as though you suspended the measurement session. 

• To resume a suspended measurement, in the Charts list, select any chart and then click Measure. 
  ColorFlow will give you the option to resume the suspended measurement, or delete it and start a new measurement.
