Hioki RM3544 resistance meter

The Hioki Model 3544 resistance meter is a four-terminal instrument providing a basic resolution of 1 µΩ and has a large measurement range from 30 mΩ to 3.5 MΩ at a maximum measurable current of 300 mA. The 3544 is suited to applications including motor windings, solenoid and relay coils, chokes and transformers, wiring harnesses, switches etc. Analysis time is typically 23 ms when employing the standard 50 Hz line voltage power source.

The instrument is available with a comparator option with audio alarm, suitable for quality inspection purposes. An optional temperature sensor is also available allowing cross-correlation with resistance measurements using input temperature coefficients.

The 3544 is available with various output options including a USB port, RS232 port and printer port. It readily integrates with ATE systems via NPN/PNP compatible I/O support. The power supply is suitable for a wide range of input voltages from 100 to 240.
