Product description:

Digital voltmeter (with RS485 communication interface and alarm control settings)

Digital instrumentation for the new generation of programmable intelligent voltage, current meter, mainly for electrical lines AC or DC voltage, current real-time measurements and instructions, and via the RS485 interface or analog transmit output interface for remote data measured power Biography. has high accuracy, good stability, long-term adjustment-free, you can set parameters panel key site features, is ideal for the original pointer instrument or general digital instrument replacement product.
• Technical Features
This series of instruments uses large scale integrated circuits, high-performance single-chip microprocessor, the application of digital signal processing technology and SMT technology is designed in a modular fashion, with switching output (upper and lower alarm) modules, analog transmit output module, RS485 digital communication module for users to choose, the modules are designed using plug mode, the user can be the instrument of functional modules freely combined and decrease can be easily achieved through the instrument instrument transformer ratio on the keyboard, set the lower limit alarm value (or range) and alarm switching difference, mailing address and communication baud rate, transmission output and transmission output range, the digital filter coefficients and other parameters. Instrument calibration potentiometer internal canceled using software transfer school approach to production, modular and universal design approach significantly reduces the production cost of the instrument, so that the series of instruments has a very high price.
