DESCRIPTION: The Krohn-Hite Model 511 Precision
DC Source/Calibrator is a secondary standard that is highly stable and repeatable from ±100nVdc to ±10Vdc, providing N.I.S.T. traceable
voltages for use in production, calibration labs, QA and QC departments, design labs, or any place where an accurate
voltage is needed. Using state-of-the-art reference, the 511 provides extremely accurate (±10ppm) and stable (±2ppm for 24 hours)
voltages over 3 ranges, allowing the output to be set from ±100nVdc...
