I'm reading the brochure for the OCE PlotWave 450/550. On page 9. I'm reading that the device will scan 47.9'/minute. Rounding off we get 48'. Thus to find the speed of inches per second I need to take 48x12=576 inches and then divide that by 60 seconds for a speed of 9.6 inches per second. Is this true?
If so, that's really fast when compared to other devices. Can someone clarify?
