Screen save
Selects whether to save the displayed screen as a BMP file at the specified interval.
The shortest interval is 5 minutes. If a value of less than 5 minutes is specified, the
screen will be saved every 5 minutes. Screen copies cannot be saved in the instru-
ment’s internal memory. To save screen copies, set the save destination to [SD
CARD].
• Ordinarily, select “Average only.” When you wish to save data
such as the following, select “All (average, maximum, and mini
-
mum values)”:
Maximum: To check maximum values for current, powe
r, etc.
Minimum: To check minimum values for voltage, power factor,
etc.
• Because the voltage and current peak va
lues are not average
values, peak values will not be output when “Average only” is
selected. To check peak values, select “All data.”
• When a “Current only” connection is bein
g used, average values
are not used for the current fundamental wave phase angle.
• Average values are calculated from the results of continuous cal-
culations performed every 200 ms during
the save interval.
• Maximum and minimum values indicate the largest and smallest
results obt
ained from continuous calculations performed every
200 ms during the save interval.
• For more information about how average, maximum, and mini-
mum values are processed, see "Maximum/minimum/average
value processing methods" (p. 195).
• Recording and measurement data
(CSV form
at) (including val-
ues such as normal voltage, current, power, demand, and
energy) and harmonic m
easurement data (binary format) are
saved in different files.
See:Chapter 8, "Saving Data and Manipulating Files" (p. 113)
