RECORD
ON COMMAND
WHY ROC?
The Record On Command feature is a means of extending record
time on those applications where you wish to capture a number
of iterations of a repeating motion.
Let's imagine a piston traveling up and down. You are specifically
interested in what is happening when the piston reaches the top
of its stroke. If you use the REC STOP mode with 1.6 seconds of
record time available you would capture 8 cycles of the piston,
assuming a speed of 300 rpm. The action that interests you all
happens in the 10 frames as the piston reaches the end of its
travel. If you could record just those 10 frames for each cycle,
you would have enough record capacity to capture 160 cycles.
ROC is the answer to this need.
