Instrument designed for analysis on electronic components, especially those with very low resistance such as shunts, the RM-3543 milliohmeter ensures extremely high-precision and extremely low-resistance measurements: up to 0.1 mΩ with an accuracy of 0.16%.

Guarantees exceptional repeatability of the measurement: simple to program, the insertion of numerical values ​​is facilitated by the appropriate keypad and the function keys (the high-contrast LCD display allows easy reading).

The RM 3543 is equipped with a specific function that allows you to check the differences between the measurement on the insulated component and the measurement on the component mounted on the board. Test current up to 1 A, the instrument is equipped with a specific function that allows to reduce overheating by applying the current only during the measurement phase.

Designed to be easily integrated into production lines where it allows to reduce test times thanks to the high response speed (2ms). 7 measurement ranges from 10mΩ to 1000Ω. Measurement range from 0.01 μΩ to 1.20 kΩ. The 6-digit RM3543 bench-top millio meter can store up to 30,000 test results.

Typical applications: shunts, resistors of very low value, resistors in general, inductors, and electronic components in general.

To be integrated on automatic machine, test current up to 1A, 6 1/2 digits, 0,16% accuracy, 0,01μΩ resolution.

Ultra-accurate and high-resolution resistance meter ideal for incorporation in automated systems

  • Advanced enough to measure 0,1mΩ ±1% shunts with room to spare
