各位大俠，小弟現在做個(gè)關(guān)于壓力的項目，壓力傳感器是電壓輸出0-10V   量程是0-20kG   分辨率是6000    現在問(wèn)題是我一上電 壓力傳感器上沒(méi)有壓力，但是也會(huì )有數據輸出大約是96左右，請教各位大俠該如何歸零啊，還有就是現在我用手去壓傳感器數據會(huì )變小，請教是怎么會(huì )事��？

接線(xiàn)：壓力變送器0-10V三根線(xiàn)，紅色接24V+,藍色接24V-,黑色接PLC的90端口VIN0，COM0接24V-即可。關(guān)于去零點(diǎn)，采用APR進(jìn)行零點(diǎn)校準。注意一下，在PLC設置界面勾選一下90端口的模擬量信號范圍。
