The RM3544 is capable of performing high-speed, high-precision measurement of the
winding resistance of components such as motors and transformers, the contact resistance
of relays and switches, the pattern resistance of printed circuit boards, and the DC resis-
tance of fuses, resistors, and materials such as conductive rubber using four-terminal mea-
surement. Since the instrument incorporates a temperature correction function, it is
particularly well suited to the measurement of targets whose resistance values vary with
temperature.

1.1 Product Overview and Features
• Installed footprint: 215 mm × 166 mm
Compact footprint and limited depth leave plenty of work space in front of the instrument.
• Measurement range: 30.000 m to 3.0000 M with a basic accuracy of 0.02%
rdg.
• Maximum measurement current: 300 mA
Ensures stable measurement, even when there is a significant amount of external noise.
• No need for warm-up operation or zero-adjustment
Since wasteful wait times are not required, you can start making measurements as soon as
the instrument is turned on.
• Choice of interfaces
RM3544 (no interface), RM3544-01 (USB, RS-232C, EXT I/O)
