RS925D Decade Resistance Standard.
RS925D Decade Resistance Standard is a four-terminal,
continuously variable resistance standard. Values from 10mΩ
to 1.2MΩ can be achieved
using eight decade switches.
The rheostat offers a resolution of 20mΩ.
Use of Evanohm, wire-wound precision resistors provide an accurate,
stable standard with good temperature characteristics.
The Model RS925D can be used as a standalone
resistance standard or in conjunction with the Models 801B/801C,
and 240C to complete a 242D or
242E Resistance Measurement System.
