3000HR High Value Resistance Standard

3000HR High Value Resistance Standard



  • Electrometer currents to 10nA
  • Resistance from 1 Mohm to 100 Gohm
  • Traceable to 1 GOhm standard
The 3000HR provides a traceable source for high value resistances, consisting of a buildup box of 1 GOhm and 10 Gohm resistors, allowing a buildup to 100 Gohm.

High value resistance standards are required by many laboratories for calibration of modern multimeters with extended resistance ranges, however they are costly and difficult to maintain.

With the 3000HR, by comparison to a 1 GOhm standard values of up to 100 GOhm can be generated.

To assist with automating the calibration of sensitive electrometers, a RS232 interface is provided to switch decade values from 1 MOhm through to 100 GOhm, suitable for resistance calibration and low current sourcing.
