Wavetek / Calibrator / 4708/10/20/30/80 
Datron AC/DC Multifunction Calibrator 

The Wavetek/Datron 4708 AC/DC Calibrator (AUTOCAL MULTIFUNCTION STANDARD) is a
 high precision calibrator and covers a wide range of DC, AC, current and resis
tance functions in a single unit. The 4708 consists of a mainframe that uses a
 microprocessor for control management for specifying its use in complex, manua
l operations of calibration of high quality digital multimeters. Includes IEEE-
488 interface for programming capabilities. The unit incorporates a reference m
odule for high accuracy over ambient temperature ranges of 23C 10C. A high leve
l of stability is achieved through selected reference components and ultra-wide 
gain-defining resistors. The output frequency extends from 10Hz to 1Hz at a res
olution of 1%.
