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
