To save a measurement simply press the red Stop button, then the Save icon at bottom right.

The time for each measurement is based on the Frame Average. The default Frame Average value of 20 provides a good balance of averaging measurements and a fast response between scans. Adjusting the Frame Average value to a smaller value, for example 10, will average less frames and make it more responsive. Increasing the Frame Average value will slow down the responsiveness but could improve the result by averaging more measurements.
