This example introduces a method to connect an instrumentation device with 4-20 mA
output and measure current variations. The average value is recorded every minute.
Connect a 4-20 mA output device and record the average value
every minute

Configure Measurement Settings
On the [Setting] screen, set the recording interval and recording time, and enab
auto saving and numerical value calculation.
1
Setting Example
To record at every 5-second interval for one hour, with auto saving to CF card, and recording calculated
values every minute along with measurement data:
Interval: 5s, Cont: Off, Record time: 1 hour
Numerical Calc.: On, Calc1: Average, Split Calc: On, Length: 1 min
Auto Save: WCalc, Split Save: Off, Media: CF
Select 50 or 60 Hz to match
the local line frequency.
Measurement Hints
Filter : When 50 or 60 Hz is selected, longer recording intervals produce lower cut-off frequencies and
better noise suppression.
The default settings for the non-
framed items can be left as-is.
Change as needed.
