Portable DC Resistance Meter 3548

The Hioki RM3548 is a handheld instrument designed to measure resistance on large equipment. Its portable form factor includes a neck strap so technicians can keep the meter close while moving around a worksite. It suits electrical maintenance teams and field engineers who need to verify connections without a bench setup. The meter covers a range from 3mΩ to 3MΩ for diverse low-resistance tasks.

Replaces bench meters for on-site work

This unit upgrades from stationary resistance meters when measurements must be taken at the equipment rather than in a lab. The jump is worth it for crews who regularly test busbars, transformer windings or motor coils in situ and cannot bring the asset to a bench. It is not for users who require automated data logging or multi-channel scanning beyond the meter's single-input design.

Highlights

  • Measure large-equipment resistance easily

Questions about this item

How do I wear the Hioki RM3548 around my neck during use?

The meter includes a strap that attaches to the body so the unit hangs securely while you move between test points.

What is the correct way to connect the test leads for a four-terminal measurement?

Plug the current and sense leads into their labelled terminals, then contact the device under test with the sense clips inside the current clips to eliminate lead resistance.
