现货供应4708万用表校准仪!

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