YHS705 Loop Calibrator is a handheld multi-function digital calibration instrument that is featured with high accuracy, resolution and reliability and anti-drop and is integrated with digital display of DC voltage, current signal source and DC voltage, DC current functions. The instrument uses large liquid crystal display with clear reading and is featured with backlight reading hold and auto power-off. The instrument can be fed by DC or AC power source, which delivers more convenience.
Signal output and mA, mV measurement functions of this instrument are mainly for field calibration, service in industrial automation site. It is an ideal tool for field metermen, distributed control system maintainers and instrument installers. It is different from common electrician multimeters and signal sources, which is the multimeter used by metermen.
The overall machine circuit takes dual slope A/D converter as its core, and is featured with signal output and measurement functions. Its technical performance conforms to Automation Instrument Calibration Standard for type Electric II and Electric II, its operation environment complies with related regulations in GB6587.1-86 Environmental tests program for electronic measuring instruments about instrument Group II.
