3000HR High Resistance Buildup Box
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

1 to 10 GOhms Resistor Bank
Link 1 GOhm resistors together to provide decade values from 1 GOhms to 10 GOhms
10 to 100 GOhms Resistor Bank
Link 10 GOhm resistors together to provide decade values from 10 GOhms to 100GOhms
Resistor banks provide the ability to link each resistor together to obtain a combined measured value from the sum of the resistor bank.
