Details

The Hioki RM3548-50 Precision Handheld Resistance Meter measures from 0.1 μΩ to 3.5 MΩ - it offs effortless operation and accuracy, making it ideal for EV maintenance, aircraft overhaul, motor inspections, and cable management.

Leveraging its precision, the RM3548-50 goes beyond basic resistance measurement. It not only performs temperature corrections, but also converts resistance to estimated motor temperatures and calculates cable lengths within 1 cm. Its versatility is enhanced by its compatibility with many specialized probes - like high-durability pin-types and needle probes (probes not included) - that measure through paint and meet various maintenance needs. Advanced connectivity enables seamless wireless data output for the efficient recording and management of measurements. Ensuring precise readings with a four-wire method and offset voltage compensation (OVC), the RM3548-50 is a go-to, dependable tool for precision maintenance.

EV and hybrid cars

Ideal for EV and hybrid car maintenance, the RM3548-50 excels in equipotential bonding tests, battery connection checks, and motor winding inspections. Compliant with UN ECE R100 standards, it offers dedicated probes (probes not included), straightforward resistance measurements, and a PASS/FAIL function. The red backlight ensures user safety by warning technicians, if a probe mistakenly contacts the battery. This device provides reliable and precise diagnostics for optimal vehicle performance.

Aviation

Also designed for aircraft maintenance and overhaul, the RM3548-50 performs equipotential bonding tests to check resistance differences in various areas. The L2141 probe (probe not included), with its rounded tip, is perfect for measuring resistance without damaging the aircraft body. Likewise, the sharp edge of the L2142 probe (probe not included) allows for resistance measurements through paint. It can also store up to 1000 data entries and offers real-time wireless data transfer to mobile devices, enhancing reporting and efficiency.

Industrial motors, transformers and power supply equipment

The RM3548-50 is perfect for industrial applications, as well - measuring resistance in motors, transformers, and power supply equipment. Applying a high current of 1 A to measure, this meter measures lower resistance values with a resolution of 0.1 μΩ. This makes the RM3548-50 ideal for verifying connection integrity in large transformers, wiring and busbars. Additionally, it predicts maximum temperature increases in motor windings and transformers using resistance measurement. Its interval measurement function records data at user-specified intervals for easy temperature estimations.

Cable

The RM3548-50 includes an automated wiring-length calculation function. By inputting a resistance value per 1 meter of cable, this meter can convert resistance values into cable lengths, making it useful for managing cable inventory or estimating PCB pattern lengths.
