Fig. 23 shows the capture of successively lower-valued signal maxima. Here, it is
necessary to reset the "+PEAK" reading—to get it "back on track," so to speak—
somewhere along the rise of the input toward the second, lower-valued peak (P
2
).
This is done by returning the unit momentarily to "TRACK" MODE at time t
2
.
