Standard reference resistors - ASL/WIKA

The ASL/WIKA standard reference resistors are available in two series: CER6000-RR (reference resistor) and CER6000-RW (standard reference resistor). The RR series of 4-wire reference resistors offer high accuracy and stability at an economic cost. Designed specifically for use as a comparison standard for AC thermometry resistance bridges of the ASL range, the RR series may also be used in electrical standards laboratories.

In addition to standard fixed values, resistors can be supplied in any value between 1 and 1,000 Ω. Typical applications for the RR series are as transfer standards or reference source in temperature calibration or electrical standards laboratories.

The RW series is made from a specially selected alloy having a low temperature coefficient mounted in a strain-free manner on formers made from a material of low dielectric loss but of high mechanical stability.
