Hioki RM3548-50 Resistance Meter
The RM3548-50 replaces the RM3458. This precision handheld resistance meter measures from 0.1 µΩ to 3.5 MΩ. Ideal for EV maintenance, aircraft overhaul, and motor inspections, this updated unit includes Bluetooth wireless connection to the mobile or PC app, 60v voltage protection, and no includes a silicone protector.
Recommended by leading EV and hybrid manufacturers for reliable and precise maintenance tasks, the RM3548-50 meets the UN ECE R100 international safety standards, which require a minimum measurement current of 0.2 A. Reliable electrical test tools to ensure safe operations for EV maintenance and service personnel.
Key Features
- 0.02% basic accuracy, 0.1 µΩ max. resolution, 1 A max. testing current
- Measure from 0.1 µΩ (testing current 1 A) to 3.5 MΩ
- Automatic temperature correction ensures accurate results & faster testing
- Advanced Connectivity: seamlessly integrate data with Excel® and a mobile app to manage & analyze data efficiently (Wireless Adapter Z3210 is necessary)
- Protections for safe operation: halts operation & triggers alerts when incorrect voltage inputs are detected
- In EV maintenance or battery busbar testing, accidental contact with live voltage can damage a resistance meter. The RM3548-50 features automatic overvoltage protection to prevent this, stopping measurements and safeguarding the circuit from live voltages of up to 60 V DC.
Versatile probing options
- A diverse range of probes are available, tailored to meet specific maintenance needs across various applications.
- L2140: 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, straightforward resistance measurements, and a PASS/FAIL function.
- L2141, L2142: Ideal for aircraft maintenance and overhaul, the RM3548-50 performs equipotential bonding tests to check resistance differences in various areas. The L2141 probe, with its rounded tip, is perfect for measuring resistance without damaging the aircraft body, while the L2142 probe’s sharp edge allows for resistance measurement through paint.
