Your local contact:Resistance testers
SCHLEICH's resistance testers are specifically designed for high-precision measurements of electrical resistance in windings, coils, and resistive elements. They are used wherever the quality and functionality of electrical components need to be reliably assessed—from manufacturing to maintenance.
These resistance testers utilize precise current and voltage measurement and, when necessary, employ four-wire measurement (Kelvin measurement) to measure even extremely low resistance values down to the µΩ range. By eliminating lead and contact resistance, four-wire measurement enables highly accurate results—even for test objects with very low resistance.
Since the resistance of copper windings varies with temperature, resistance testers are equipped with temperature compensation. This feature allows measured values to be converted to reference temperatures (e.g., 20 °C) in accordance with standards. This ensures reproducible and comparable measurement results—regardless of environmental influences. Various measurement methods are available for temperature measurement.
Key Facts:
- Wide measurement range: from a few µΩ up to the kΩ range
- High accuracy thanks to four-wire technology and temperature compensation
- Fast and repeatable measurements

Good to know:
The Resistance Test
An ohmic resistance measurement is used to determine the electrical resistance of a component or conductor. It is based on Ohm's law:
whereas
- R = Resistance in ohms (Ω)
- U = Voltage across the resistor in volts (V)
- I = Current in amperes through the resistor (A)
How is the measurement performed?
There are two common methods:
- Measuring resistance with an ohmmeter (multimeter in resistance mode)
- The device applies a test voltage—often very low—and measures the current flow.
- The resistance is calculated and displayed based on this.
- Disadvantage: Often inaccurate, especially for resistances below 10 Ω.
- SCHLEICH Principle: Maximum accuracy through resistance measurement with a constant test current and precise voltage measurement
-
- Advantage: Four-wire measurement
- Advantage: High accuracy even for resistances less than 1 mΩ
- Advantage: Temperature compensation of the measured resistance (particularly important, for example, with copper wires)
- Advantage: Temperature sensor measurement with temperature compensation
