Description
RM3548-50 Resistance Meter for High-Precision Maintenance and Testing
The RM3548-50 Resistance Meter is engineered for professionals who demand precise, reliable resistance measurements across a broad range of applications. Measuring from 0.1 µΩ to 3.5 MΩ with 0.1 µΩ resolution, it provides unparalleled accuracy for critical maintenance tasks in electric vehicles, aircraft, and motors. Its four-wire measurement system, combined with offset voltage compensation (OVC), ensures stable readings even in complex wiring conditions, making it perfect for detecting minute changes in resistance that indicate potential faults.
Designed for ease of use, the RM3548-50 automatically corrects for temperature variations, converting resistance readings to accurate values at a reference temperature. This allows technicians to assess component performance immediately without waiting for cooling periods, reducing downtime and improving workflow efficiency. The device also converts resistance into estimated motor temperatures and calculates cable lengths with 1 cm precision, enhancing operational insights.
The meter supports advanced connectivity through the optional Z3210 Wireless Adapter, enabling Bluetooth® integration to smartphones, tablets, or Excel® templates. This feature streamlines reporting and data management, ideal for modern maintenance environments. For safety, the RM3548-50 features active circuit protection, stopping operation and triggering alerts if overvoltage conditions are detected.
Versatile probe options expand the meter’s applicability:
- L2140 for EV and hybrid vehicle maintenance, including battery checks and motor winding inspections.
- L2141 & L2142 for aircraft maintenance, providing safe and precise resistance measurements on painted surfaces or delicate structures.
Compliant with UN ECE R100 standards for high-voltage EV maintenance, the RM3548-50 is the ultimate precision tool for professionals who require accuracy, safety, and efficiency in one portable device.
