HIOKI RM3548 Micro-Resistance Meter

The HIOKI RM3548 micro-resistance meter is a portable high-precision instrument designed for measuring resistance in the range from micro-ohms to mega-ohms. It is ideal for testing and servicing large equipment, such as windings and welded joints in large motors and stators of hybrid and electric vehicles.

Main Features of RM3548

• Resistance measurement range: from 0.0 µΩ (at a test current of 1 A) to 3.5 MΩ.
• Basic accuracy: ±0.02%.
• Maximum resolution: 0.1 µΩ.
• Maximum test current: 1 A.
• Built-in memory: ability to store up to 1000 data points.
• Interfaces: USB for data transfer.
• Additional functions: offset voltage correction (OVC), temperature correction, and automatic data saving.

Advantages

The portable design of the RM3548 makes it convenient for field use, especially for servicing large equipment. The device can operate on eight AA batteries, providing approximately 10 hours of continuous operation.

Additional Features

For temperature measurement, the RM3548 is equipped with a Z2002 temperature sensor, allowing for temperature correction and ensuring high measurement accuracy.

The device also supports various measurement accessories, including clip-type and pin-type probes, expanding its functionality and allowing it to adapt to different tasks.
