因此為了得到輸出電壓誤差，反饋電阻的取值應(yīng)該很大。由于3V工作電壓時(shí)，MAX4544的導(dǎo)通電阻僅為120Ω，因此開(kāi)關(guān)MAX4544引入的誤差電壓很小，即使低輸出電壓也是如此。當(dāng)使能升壓變換器，且其輸出電壓超過(guò)MAX810的復(fù)位門檻電平并經(jīng)過(guò)復(fù)位延遲后，MAX810的輸出將由高變低，使Q1導(dǎo)通，連通負(fù)載。同時(shí)，MAX810輸出的低電平使MAX4544的COM端與NC端（常閉端）接通，使得反饋電阻由Q1的源極切換至Q1的漏極，從而允許從遠(yuǎn)離變換器的負(fù)載端對(duì)輸出電壓進(jìn)行調(diào)節(jié)。上述MAX4544的開(kāi)關(guān)過(guò)程也把MAX810的輸入端從Q1的源極切換到Q1的漏極，這樣一來(lái)，MAX810可以用來(lái)監(jiān)測(cè)負(fù)載是否過(guò)載。

光纖水位計(jì)光纖水位計(jì)包括水位計(jì)傳感器部分和控制電路終端部分。其中，水位計(jì)傳感器部分采用光路耦合調(diào)節(jié)設(shè)備與光纜連接用于傳遞承載水位信息的光信號(hào)，控制電路終端部分采用激光調(diào)制技術(shù)，發(fā)送不同功能的調(diào)制激光信號(hào)，通過(guò)調(diào)制、對(duì)比與檢測(cè)，獲得水位的準(zhǔn)確信息。這一原理實(shí)現(xiàn)了全程光測(cè)量，在室外不使用任何帶電器件，可以杜絕靜電危害防止雷電擊毀。跟蹤式水位計(jì)又稱接觸式水位計(jì)，利用重錘上的電測(cè)針接觸水面發(fā)出電信號(hào)，使電機(jī)正轉(zhuǎn)或逆轉(zhuǎn)，隨時(shí)跟蹤水面點(diǎn)的位置，從而測(cè)定水位。一般在較陡岸坡上架設(shè)鐵管，懸錘和懸索在管道中升降，驅(qū)動(dòng)記錄或訊號(hào)裝置。鐵管進(jìn)水口需有沉沙和靜水設(shè)施。壓力式水位計(jì)它的工作原理是測(cè)量水壓力，推算水位。其特點(diǎn)是不需建靜水測(cè)井。

其范圍為2-9.9倍，撥碼左邊一個(gè)表示1倍，右邊一個(gè)表示0.1倍。當(dāng)其值為0時(shí)則為3倍。若設(shè)定電流為2.6A，速動(dòng)倍數(shù)為3倍，則當(dāng)電流達(dá)到3×2.6=7.8時(shí)，會(huì)不經(jīng)延時(shí)而直接動(dòng)作。注意，無(wú)輔助電源產(chǎn)品速動(dòng)后斷電方可返回。新產(chǎn)品，采用導(dǎo)軌和固定安裝型，采用PLC型外殼，體積小，安裝方便，度高，是非常理想的產(chǎn)品。測(cè)試項(xiàng)目編輯觸點(diǎn)電阻用表的電阻檔，測(cè)量常閉觸點(diǎn)與動(dòng)點(diǎn)電阻，其阻值應(yīng)為0，(用更加方式可測(cè)得觸點(diǎn)阻值在100毫歐以內(nèi))；而常開(kāi)觸點(diǎn)與動(dòng)點(diǎn)的阻值就為無(wú)窮大。由此可以區(qū)別出那個(gè)是常閉觸點(diǎn)，那個(gè)是常開(kāi)觸點(diǎn)。線圈電阻可用表R×10Ω檔測(cè)量繼電器線圈的阻值，從而判斷該線圈是否存在著開(kāi)路現(xiàn)象。吸合電壓電流找來(lái)可調(diào)穩(wěn)壓電源和電流表。
