The Keithley Instruments Model 2600-STD-RES 1G 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. Similar current-sourcing and measuring instruments and other Series
