Electronic Development Corp MV-106 DC Voltage Standard

The EDC MV-106 is a precision DC voltage standard designed for applications requiring highly stable and accurate voltage outputs. This instrument is suitable for use in standards laboratories, automated calibration systems, production line testing, and as a reference for computer systems. It utilizes a chopper-stabilized amplifier for maintaining output stability and a temperature-compensated, aged zener diode as its voltage reference. The device offers multiple voltage ranges and high resolution, enabling precise calibration of various measuring instruments.
