Checking recording conditions with the fluctuation graph
HARMONICS
The horizontal scale of the fluctuation graph are changed automati-
cally during recording.
If you want to change the scale, you must stop recording first.
All calculation items that can be displayed for harmonic fluctuation
are calculated without gaps every 200 ms. (Every 10 cycles at 50 H
or every 12 cycles at 60 Hz.)
MAX, MIN, and AVE values are recorded every 200 ms for the set
interval. The graph displays values such the MAX, MIN, and AVE va
ues as a single line.
Example: When the interval is set to 1 m:
The MAX, MIN, and AVE values are recorded for 300 points of data
recorded every 200 ms.
