KROHN-HITE 523 Precision DC Source
The Krohn-Hite Model 523 Precision DC Source is a highly stable and repeatable dc voltage source and dc cur source providing N.I.S.T. traceable voltages and currents for use in production, calibration labs, QA and QC departments, design labs, or any place where an accurate voltage and cur source is needed. Using Krohn-Hite's state-of-the-art reference, the 523 provides accurate and stable voltages from ±10nVdc to ±110.99999Vdc to within ±4ppm for 90 days ( ±8ppm for 1 year), and precise currents from ±10nA to ±110.99999mA to within ±8ppm for 90 days ( ±16ppm for 1 year).
The Krohn-Hite 523 features a user friendly 7 ½ digit display and a membrane keyboard entry of all settings. Output settings can be modified using a plus/minus delta function, multiply/divide function and cursor control keys that allow placing a curse on any digit to increment or decrement its value. Output 2-wire, 4-wire and chassis grounding are accomplished with one keystroke or over the GPIB interface bus. A crowbar function places the output in a safe mode when desired. The 523 output can be set to 0 volts, allowing the output sense to maintain a true 4-wire low impedance zero output. It is also quickly forced to zero before a range change to prevent any "surprise voltages" from appearing.
