Description: Keithley Picoampere Passive Source Model: 261Description: The Model 261 Picoampere Source is a secondary standard for use in calibrating picoammeters and electrometers. The output of the Model 261 can be adjusted between 10-‘4A and 1.1 x 10.4A in eight decade ranges. The source has 3 digit resolution for current outputs b#etween 10~12 and 10~4A. The current output of the Mlodel 261 is derived from a variable voltage source and a selectable range resistance. The voltage supply is highly ragulatled for stability and uses highquality components throughoul for reliability. The low side of the output can be floated to avoid possible ground loop problems.
