短路檢測：在保證安全的情況下，將相關(guān)部分回路直接短接，如：差變送器輸出值偏小，可將導(dǎo)壓管斷開，從一次取壓閥外直接將差壓信號直接引到差壓變送器雙側(cè)，觀察變送器輸出，以判斷導(dǎo)壓管路的堵、漏的連通性。在儀表維護(hù)中，由于差壓變送器導(dǎo)壓管排放不及時，或介質(zhì)臟、粘等原因，正負(fù)導(dǎo)壓管堵塞是經(jīng)常發(fā)生的事，通常正導(dǎo)壓管堵塞的現(xiàn)象是：變送器輸出下降、上升或不變。當(dāng)流量增加時，對變送器(變送器本身進(jìn)行輸出信號開方)輸出的影響由于正壓管堵塞，則當(dāng)實際流量分別為FF1時，P1+=P2+；當(dāng)實際流量由F1減小到F2時，管道中的靜壓也相應(yīng)的降低，設(shè)降低值為P；同時，當(dāng)實際流量下降至F2時，P2-值也要因為管內(nèi)流體流速的降低而升高，設(shè)升高值為P。
