The 3000RS is a dedicated precision resistance standard. The standards do not require temperature controlled air
or an oil bath making the 3000RS suitable as working standards, transfer standards as well as calibration support
for the 3000 series range of multi product calibrators.

The 3000RS is built using oil filled hermetically sealed ultra high precision foil resistors from 1 Ohm to 100kOhm,
and oil filled hermetically sealed ultra high precision wire wound for the 1 MOhm.
