RR Standard
Reference Resistor. Resistance Standard Accuracy +/- 0.01%
RR Standard Resistors series of 4 wire reference resistors offer high
accuracy and stability at an economic cost.
Designed specifically for
use as a comparison standard for resistance thermometry on the ASL range
of AC resistance bridges, 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 1000 Ohms. Typical applications for the RR series
are as transfer standards or reference source in temperature calibration
or electrical standards laboratories
