Peak/Smooth - AEMC 725 User Manual

Peak/Smooth

Peak
Peak is a fast responding function which measures the instantaneous (1
ms) Peak values of the measured signal. This function is often used for
half cycle in-rush signals. Peak measurements are accessed with a single
push of the yellow (Shift) push button. The Peak function is displayed in
the lower right-hand corner of the display next to the measurement sym-
bol. Control is verified with a short beep.
Peak may also be accessed when recording. In recording MIN/MAX,
depressing PEAK gives the MAX Peak.
The bar graph also indicates the Peak values. When a Peak value exceeds
the bar graph scale, an arrow at the end of the scale is displayed.
will select either positive (+) or negative (-) peaks.

Smooth
Smooth stabilizes the digital readings when measurements fluctuate. In
this mode, the Model 725 calculates and displays a three-second average
reading. Smooth may be used in volts, amps, and frequency, as well as
power quality functions (%THD, %DF, CF).
Use the SMOOTH push button. Control is verified with a short beep.
Smooth may be used while in the MIN/MAX recording mode. The ana-
log bar graph will not be affected by the Peak/Smooth functions, and
continues to display Arms or Vrms.
