Peak; Min/Max Push Button: Recording Function - AEMC 721 User Manual

5.6.2 Peak

Peak is a fast responding function which measures the instantaneous
(1ms) Peak values of the measured signal. This function is often used for
half cycle in-rushing signals. The Peak function is displayed in the lower
right-hand corner of the display next to
the measurement symbol.
Peak may also be accessed when record-
ing. When recording MIN/MAX, depress-
ing PEAK gives the MAX Peak only.
The bargraph also indicates the Peak
values. When a Peak value exceeds
the bargraph scale, an arrow at the end
of the scale (►) is displayed. When in
MAX Peak, the MAX Peak value blinks
while the bargraph continues to respond
in Peak mode.
