5.6.1 Smooth

Smooth stabilizes the digital readings
when measurements are fluctuating. In
this mode, the Model 721 calculates and
displays a three-second average reading.
Smooth may be used in Volts, Amps, Fre-
quency, as well as power quality functions
(%THD, %DF, CF). Smooth may also be
used while in the MIN/MAX recording
mode.
The analog bargraph will not be affected
by the Smooth functions and continues to
display Arms or Vrms.
