HIOKI – RM3548

Since the RM3548 provides an interval measurement function that can take readings continuously at an interval as short as 0.2 seconds, the instrument is ideal for use in temperature testing.

RESISTANCE METER RM3548 Features

  • 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 mΩ to 3.5000 MΩ.
  • 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.

Since the RM3548 provides an interval measurement function that can take readings continuously at an interval as short as 0.2 seconds, the instrument is ideal for use in temperature testing.
