Universal power supply for robust accom-
modation of supply voltage fl uctuations
and automatic power supply frequency
detection (RM3544/RM3544
-01)
Measuring in sync with the power line frequency is important for
achieving accurate measurements. To avoid measurement prob-
lems due to incorrect settings, the power line frequency is auto-
matically sensed and selected (50 or 60 Hz).
The universal AC input (90 to 264 V) is practically unaffected by
voltage fl uctuations, so stable measurements are possible even in
poor power environments.

Connecting the instrument to a computer
via RS-232C or USB
• The full range of RM3544-01 functionality can be controlled from
a computer, which can also be used to acquire measurement results.
(This capability does not include turning the instrument on and off
or confi guring certain interface settings.)
• By connecting the instrument to a commercially available RS-232C
printer, it you can print measured values, including judgment re-
sults.
• The keyboard-class USB interface enables the RM3544
-01 to auto-
matically output measured values. This capability allows measured
values to be input into applications such as spreadsheets and text
editors without the need to install a special USB driver on the com-
puter.
• Use HIOKI freeware to download data to a computer, perform in-
terval measurement, conduct a communications test, load acquired
data into Excel, and output acquired data as a CSV fi le in response
to a trigger signal. Freeware can be downloaded from the HIOKI
website.

Communications monitor function for smooth
system development
The communications monitor function displays communications data
(received commands and sent data) on the screen, providing valuable
support for programming of programmable logic controllers (PLCs).
