AOB194F Series digital display meters are a new generation of programmable intelligent frequency meters, which are mainly used in the real time measurement and indication on frequency of electric wiring and can remotely transmit the measured data of quantity of electricity through RS485 interface or analog quantity transmitting output connector.
With features of high precision, good stability needing no adjustment for long term, spot field setting parameters by panel keys, it is an idea upgraded product of original dial instrument or common digital instrument.
This series instruments all adopt large scale integrated circuit (LSI), high-powered single chip microprocessor and apply digital signal processing technique and SMT technics for building block design.
With free options of switching value output (higher and lower limit alarm) module, analog quantity transmitting output modular, RS485 digital communication module, each module is designed as push-pull mode and user can freely assemble, increase or decrease any functional modules of instrument according to demands.
It can conveniently realize the setting of many parameters of higher and lower limit or range alarm of instrument, alarm switching contrast, communication address and communication baud rate, transmitting output mode, transmitting output range and digital filtering mode by the keyboard of instrument.
Abolishing the adjustment potentiometers of internal instrument, adopting software adjustment mode for production and modular and generalized design mode reduce the cost of instrument production significantly, which makes the instrument highly cost-effective.
