HIOKI RM3548 Precision Portable Resistance Meter

HEAT INSULATION Portable and compact: Ideal for maintenance applications The RM3548 features a portable design that allows it to be used not only in the production, maintenance, and inspection of large coils, motors, and transformers, but also in applications such as the testing of electric vehicles, hybrid vehicles, and aircraft. Despite a portable, battery-powered design, the instrument is capable of highly reliable measurement thanks to a measurement current of 1 A, a maximum measurement accuracy of 0.02% , and a measurement range of 0.000 m© to 3.5000 M© . Interval measurement capability: Ideal for temperature testing of windings Components known as windings, which are used internally in equipment such as motors and transformers, must be tested for temperature changes to verify that they do not throw off an abnormal amount of heat when a large voltage is applied. However, because they are located inside motors and other equipment, the temperature of windings cannot be measured directly. Instead, it is typical to use a temperature testing technique in which a resistance value is measured and converted to a temperature. Features Basic accuracy: 0.02%, Max. resolution: 0.1 μΩ, Max. measurable current: 1 A Measure from 0.0 µΩ (@ 1 A) to 3.5 MΩ Easily record up to 1,000 data points in memory simply by applying the instrument’s probes. Smoothly capture temperature-rise test data using interval measurement. Portable design is ideal for maintenance and testing of large equipment. High-precision specs in a portable package(high accuracy of 0.02% rdg.) Design is ideal for maintenance and testing/measurement of large equipment. No warmup period or zero adjustment required. Dramatically improved overvoltage resistance (protection up to 70 V DC)
