1.1 Product Overview
The 3541 employs a four-terminal measurement method that is ideal
for measuring the resistance of motor and transformer windings, relay/
switch and connector contacts, PCB patterns, chip inductor DC
resistance and for ohmmeter shipping inspection tests. The instrument
includes functions for temperature correction, comparator decisions
and data output, making it particularly suitable for production and
inspection lines, as well as for system applications.
The 4-terminal method enables precise, fast measurement of
resistances as small as 0.1 µΩ.
In addition, resistance measurements can be made as in as little as
0.6 ms.
Removes the effects of thermoelectromotive force on measurements.
Minimizes stress on test objects.
A multipolar connector (INPUT B) shielded from thermoelectromotive
force is provided to facilitate fast measurements.
By connecting a temperature probe, temperature correction of
resistance measurements is available for practically any temperature
and thermal coefficient. A thermometer with analog output can be
used in place of the supplied 9451 TEMPERATURE PROBE.
