Display device of the present utility model can adopt digital the demonstration or light beam demonstration or the digital display mode that adds light beam, to show the amount or the size of measured parameter; And light beam shows and can be divided into display mode single, two, three light beams, can show single or shows the size of a plurality of tested parameters simultaneously.
Compared with prior art, the utility model be owing to will show and volume becomes to send and combines, and adopt digital display or light beam to show simultaneously or digital display adds the mode that light beam shows, so have following advantage:
1, a tractor serves several purposes: can field monitoring show the value of electric parameter, substitute existing pointer instrument, again can outputting standard simulate amount voltage signal and substitute the repertoire of existing electronics transmitter;
2, many in conjunction with electric parameter, select all can in a power meter, to be shown or export as electric weight such as P, Q, IA, IB, VAB, VBC, FT, PF flexibly;
3, degree of accuracy height: numeral shows and becomes send output accuracy to be 0.5%, can solve telemechanical image data and the inconsistent contradiction of on-the-spot table meter reading form for a long time;
4, show variable power, wide ranges: can be provided with arbitrarily at any time according to the variation that the user uses, be convenient to expand.
5, the existing numeral of display mode shows, the indication of electronics light beam is arranged again, and the digital display reading is intuitive, clear, accurate, and the voltage of three light beams, electric current can show the balance of three-phase simultaneously, more can satisfy the actual needs of field monitoring.
