resistance testers
SCHLEICH resistance testers SCHLEICH specialized designed specialized high-precision measurements of electrical resistance 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 testers operate with precise current/voltage measurement and, if necessary, use four-wire technology Kelvin measurement) tospace even extremely small resistance values down to thespace . By eliminating line and contact resistance, four-wire technology enables four-wire technology results—even with very low-resistance test objects.
Since the resistance of copper windings changes depending on temperature, resistance testers feature temperature compensation. This function allows the measured values to be converted to reference temperatures (e.g., 20 °C) in accordance with standards. This enables 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 to the kΩspace
- High accuracy thanks to four-wire technology temperature compensation
- Fast and reproducible measurements
- Can be automated for series testing
- PC interfaces for quality assurance and traceability

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:
whereby
- R = Resistance in ohms (Ω)
- U = voltage volts across the resistor (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 often TEST VOLTAGE only a very small TEST VOLTAGE and measures the current flow.
- The resistance is calculated and displayed from this.
- Disadvantage: Often inaccurate, especially with resistances below 10 Ω.
- SCHLEICH principle: Maximum accuracy through resistance measurement with constant Test current precise voltage consumption
-
- Advantage: Four-wire measurement
- Advantage: High accuracy even with resistances less than 1 mΩ
- Advantage: Temperature compensation of the measured resistance (particularly important, e.g., for copper wires)
- Advantage: Temperature sensor measurement with temperature compensation
