JS-320 係多通道、高功能、高精度、雙顯示荷重顯示控制器，最多可同時讀取4組荷重訊號。 本控制器針對應變規式感應器而設計，有絕佳之穩定性，採用快速類比數位轉換器，取樣速度 單通道最快可達每秒960次(雙通道160次)：內部解析度高達100萬，顯示解析度最高可達5萬，具有二組5位數LED顯示螢幕，將量測值與設定值分開，使量測數值與設定值易於分辦與設定 ，有18個指示燈，隨時顯示其工作狀態，特別設計的高點保持與自動復歸功能，使量測自動循 環啟動，並具備5種常用之單位轉換，具有4組設定警報輸出、類比與數位輸出介面，易於與電 腦或PLC連線。

JS-300 is a multi - channel, high quality and high precision dual - display load cell measuring controller. It can access 4 channel signals at the same time. It is special designed for strain gage load cell, processed excellent stability. It adopts high frequency A / D converter with and sampling rate is up to 960 Hz ( 2 channel 160 Hz ) ; The internal resolution ofJS-320 is up to 1000000 count ; And the display resolution is up to 50000 counts. There are two five digital led diaplay sets to separate measurement value and alarm setting value and it would be helpful for alarm setting and measurement data display. Special designed peak hold and auto  reset function make measurement automatically restart and cyclically proceed. It has 18 guiding lights for working conditions index, 5 general used unit converting, 4 setting alarms output , analog and RS-232 or RS-485 digital output interface. That makes it easy to connecting to computer or PLC.
