The 3000HR provides a traceable source for high voltage resistance, 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 but are costly and difficult to maintain confidence.
With the 3000HR, with comparison to a 1 GOhm standard, values of up to 100 GOhm can be generated.
To assist with automating the calibration of sensitive electrometers, an RS232 interface is provided to switch decade values from 1 MOhm through to 100 GOhm, suitable for resistance calibration and low current sourcing.
