RESISTANCE METER RM3544/RM3544-01
RESISTANCE METER RM3548
Temperature correction
Generally, the resistance of cooper wiring changes with temperature
by 0.4% per degree Celsius. The RM3544/RM3544
-01/RM3548
provides a temperature correction function to convert the observed
resistance value R
t at the current temperature t to the resistance
value R
to at the reference temperature t0.
*Requires temperature sensor (Z2001 or Z2002).
Reference temperature setting range:-10 ℃ to 99.9 ℃
Temperature coeffi cient setting range:-9,999 ppm to +9,999 ppm

Robust specifi cations in a compact package
Max. measurable current : 1A
Max.resolution : 0.1µΩ
Basic accuracy : 0.0 2%
for both manual operation and
integration with automatic lines
Measure from 0.0 µΩ (@ 1 A) to 3.5 MΩ
Easily record up to 1,000 data points in
memory simply by applying the instrument’s
probes.
Smoothly capture temperature-rise test data
using interval measurement.
Portable design is ideal for maintenance and
testing of large equipment.
Measure from 0.000 mΩ (@ 300 mA) to 3.5 MΩ
Probe for guard jack use and increased
measurement current yield an instrument that’s
more resistant to noise.
Optional LED COMPARATOR ATTACHMENT and
high-volume judgment tones combine to ensure
PASS/FAIL judgments are communicated reliably
in the noisy environment of the production fl oor.
EXT I/O interface with NPN/PNP support can
accommodate a variety of automated production
lines (-01 model).
