Measuring electrical resistance in the micro ohm range is crucial in the automotive industry to ensure the efficiency, safety, and performance of electrical systems. Digital micro ohm meter measuring devices are used to reliably test high-current connections, battery contacts, and components for electromobility, among other things. They are particularly important in the following areas:
In rail vehicles and commercial vehicles, it is used to check switches, conductor rails, and welds, while in aviation it is used to ensure reliable connections in safety-critical systems. In shipbuilding, it also contributes to the quality assurance of cable and distribution systems.
In electrical engineering, measuring electrical resistance is one of the fundamental tasks. Simple measurement methods are sufficient in the higher ohm range, but precise measurements for quality assurance in the micro- or milliohm range place special demands on the technology used. The choice of measurement method determines how accurate and reliable the results are.
Multimeters usually use the 2-wire method, while professional measuring systems such as the PROMET product family rely on the more accurate 4-wire or Kelvin measuring method.
In order to meet the highest quality and safety standards, the precise measurement of even the smallest resistances is essential. This is precisely where the micro-ohmmeter demonstrates its superiority over the multimeter and delivers the accurate results that are crucial.
Multimeters are commonly used for basic tasks such as testing car battery with multimeter. But when precise results in the micro- or milliohm range are required, other measurement methods can offer clear advantages.
PROMET micro ohm tester offer maximum measurement accuracy in the range from microohms to kiloohms, meeting the requirements of a wide variety of applications such as on-site measurements, industrial manufacturing, and research and development laboratories. They impress with their intuitive user guidance, low weight, compact design, and a variety of test modes. These are combined with a memory option and efficient data management of the results. PROMET micro ohm meter can be used for a wide range of applications and are available in various designs and with currents up to a power of 600 ADC.
PROMET resistance measuring devices are used by manufacturers, operators of plants, vehicles, and similar facilities, as well as service providers who use them for assembly, commissioning, acceptance, and maintenance work.
Low resistance measurements are important
In automation technology, for example in electromobility in the automotive industry, there is growing demand for accurate low-resistance measurements. The PROMET R300/R600 resistance measuring devices enable simple automation of measurement sequences via the PROMET PI programming interface. The interface can be used in COM/ActiveX and .NET environments and allows easy integration of the measuring devices into test benches. Measurements can be performed automatically after one-time programming.
