KEITHLEY 2790 SourceMeter Switch System 0.1 uV - 1000 Vdc 100 uOhm-120 MOhm Used. Works well. See photos for voltage measurement test. Does not include any leads. From the manufacturer: "Broad range of Measurement Capabilities The Model 2790’s built-in DMM can make a wide variety of general purpose measurements: • DC voltage measurements from 0 1μV to 1000V • AC voltage measurements from 0 1μV to 750V • DC current measurements from 10nA to 3A • AC current measurements from 1μA to 3A • 2-wire resistance measurements from 100μW to 120MW • 4-wire resistance measurements from 100μW to 120MW • Frequency measurements from 3Hz to 500kHz • Period measurements from 333ms to 2μs • Temperature measurements from –200°C to 630°C (thermistors and 4-wire RTDs) Additional features of the Model 2790 mainframe include: • Setup storage—Up to four instrument setups can be saved and recalled • Offset-compensated ohms—A two-measurement process for 4-wire ohms to cancel the effects of thermoelectric EMFs Available for the 100W, 1kW, and 10kW ranges • Math—m/X+b, mX+b, percent, and four special math functions provide convenient manipulation of raw readings • Relative—Null offsets establish baseline values • Ratio and channel average—Ratio and average calculations for two switching module channels (7702) • Buffer—Store up to 55,000 readings in the internal buffer • Limits—Two sets of high and low reading limits to test devices • Digital I/O port—Five digital limit test output lines to control external circuitry An external trigger input can also be accessed at this port • Trigger Link—Separate connector with input and output signals • Monitor—The Model 2790 can monitor a selected channel A scan can be triggered to start when the monitor detects that a reading limit has been reached (7702) • Remote interface—Model 2790 can be controlled using the IEEE-488 interface (GPIB) or the RS-232 interface. • Programmable constant V source (50–500V) supports high speed, high resistance measurements • Programmable constant I source (0–50ma) with dry circuit clamp helps prevent device stress or damage during low resistance measurements"
