II. JDE Digital Panel Meter

1.Usage & Technique Features

This JDE digital panel meter is a new generation programmable intelligent meter, mainly used in real time measuring and indicating for various electrical parameters in the power circuits, its measured data can be remotely transmitted by 485 interface or analogue transmitting interface. Features high precision, high stability, long time operation without adjustment and on the spot parameter setting via the panel keys, it is an ideal substitute for pointer type meter or common digital meter.

It adopted large scale integrated circuit, high performance single chip, applied digital signal processor and SMT workmanship and module. With multi-channel switch module (upper & lower limit alarm), multi-channel analogue transmitting module, RS485 digital communication module available by plug-in mode, users can randomly choose the modules according to their actual need. Through the programmable keyboard of the meter, users can easily set the current transformer ratio, upper & lower limit alarm, communication port and baud rate, transmitting mode and range, digital wave filter mode and digital wave filter factor. Inside the meter, the calibrating potential indicator was replaced by a software tester. This modulized and generalized designing substantially reduced the production cost, thus the meter is of high cost performance.
