Your local contact:Resistance Test Devices
SCHLEICH resistance test devices are specialized for high-precision measurements of electrical resistances in windings, coils, and resistive elements. They are used wherever the quality and function of electrical components must be reliably evaluated – from manufacturing to maintenance.
The resistance test devices operate with precise current/voltage measurement and, if required, utilize four-wire technology (Kelvin measurement) to detect even extremely small resistance values down to the µΩ-space. By eliminating line and contact resistances, four-wire technology enables highly accurate results – even with very low-impedance devices under test.
Since the resistance of copper windings changes depending on temperature, the resistance test devices feature temperature compensation. With this function, the measured values can be converted to reference temperatures (e.g., 20 °C) in accordance with standards. This allows for reproducible and comparable measurement results – independent of environmental influences. Various measurement methods are available for temperature measurement.
Key Facts:
- Wide measurement range: from a few µΩ up to the kΩ-space
- High accuracy through four-wire technology and temperature compensation
- Fast and reproducible measurements
- Automated for series testing
- PC interfaces for quality assurance and traceability

Good to know:
The Resistance test
An ohmic resistance measurement serves to determine the electrical resistance of a component or conductor. It is based on Ohm's Law:
where
- R = Resistance in Ohm (Ω)
- U = voltage in Volts across the resistor (V)
- I = current in Amperes through the resistor (A)
How is the measurement performed?
There are two common methods:
- Measurement of resistance with an Ohmmeter (multimeter in resistance mode)
- The device applies an often very small test voltage and measures the current flow.
- From this, the resistance is calculated and displayed.
- Disadvantage: Often inaccurate, especially for resistances below 10 Ω.
- SCHLEICH Principle: Highest accuracy through resistance measurement with constant Test current and precise voltage acquisition
-
- Advantage: Four-wire measurement
- Advantage: High accuracy even with resistances smaller than 1 mΩ
- Advantage: Temperature compensation of the measured resistance (especially important, e.g., for copper wires)
- Advantage: Temperature sensor measurement with temperature compensation
