Clamping device 2381
Specification testing of copper, aluminium or brass wires
Several aspects must be considered when testing wires, such as
Copper has a temperature coefficient of about 0.4 %/K, this means if not considering the temperature at an ambient temperature of e.g. 30 °C, the measured value will be 4 % too large (based on 20 °C).
The combination of RESISTOMAT® 2316 and clamping device 2381 is ideally suited for wire cross-sections from 0.1 to 100 mm2. With the adjustable clamp support the measuring length can be varied up to 1000 mm. Although only 500 mm can be measured, the RESISTOMAT® can still show the resistance in ohms per meter. Clamping devices for larger cross-sections up 2500 mm2 are also available.
