Monitoring Voltage Fluctuations
19
This section describes voltage measurement using an AC transducer* to acquire
voltage fluctuation data for one week.
* The example transducer provides 0 - 10 V DC o
utput proportional to 0 - 150 Vrms
AC input.

Change as needed.
Setting Example
(Record at one-minute intervals for seven days automatically
on the CF card)
Interval: 1min
Record time: Cont Off, 7 days
Auto Save: Waveform(realtime)
Set the recording
interval.
Set the recording
length.
Select the save method for auto-saving.
Verify that there is enough space on the CF
Card, and that it is inserted correctly.
Enable [Deleting] (set to [On]) to delete old files when the CF card or USB flash drive becomes full.
Otherwise, when disabled (set to
[Off]), saving stops when the card becomes full. Also, when you
want measurements saved in multiple files at specific intervals, s
et [Split Save] to [On] or to [Ref
Time] and set the interval as needed.
