The RM3545 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. It also provides features such as a comparator function, communications,
external control, and a multiplexer*, allowing it to be used in a wide range of applications,
including in development work and on production lines.
* The multiplexer can be used with the RM3545-02.
