Model 2600-STD-RES Calibration Standard 1GOhm Resistor for Models 2635A and 2636A

Part Number: 2600-STD-RES

The Keithley Instruments Model 2600-STD-RES 1GΩ resistor is a precision guarded resistance standard that may be used as a high-resistance physical constant to calibrate low current instruments. An accurate current measurement may be made from the physical constants of resistance and voltage if the initial value of these constants is accurately determined. The Model 2600-STD-RES resistor is recommended for calibrating the lowest current ranges of Keithley Instruments Models 2635 and 2636.
