RM3548
High-precision specs in a portable package(high accuracy of 0.02% rdg.)
Design is ideal for maintenance and testing/measurement of large equipment.
No warmup period or zero adjustment required.
Dramatically improved overvoltage resistance (protection up to 70 V DC)
High-precision specs in a portable package
Expansive range options
Measure from 0.0 µ Ω to 3.5000 MΩ
0.1µΩ max. resolution, 0.02% basic accuracy
Max. measurable current of 1A
Continuity and resistance measurement
in large transformers, motors, and power
supply equipment
The RM3548 uses a high current of 1 A to measure lower
resistance values more reliably at a resolution of 0.1 μΩ in
applications including measuring resistance in large trans-
formers and motors as well as wiring, busbars and connec-
tions in power supply equipment.
Veri cation of continuity of ground
lines in automobiles and fuselage
welds and caulking in aircraft
The RM3548 can be used to check ground connections*
in automobiles and fuselage welds and caulking in air-
craft using a measurement current of 300 mA (300 mΩ
range).
