style="text-indent:25px">數(shù)顯儀表是一種常用的檢測儀器，具有使用簡便、可靠性高、穩(wěn)定性好、使用壽命長等優(yōu)點(diǎn)。用戶在選購數(shù)顯儀表的時(shí)候?qū)τ跀?shù)顯儀表的使用需要有一定的了解。儀表尺寸：即儀表的體積大小，這是個(gè)很基本的問題。數(shù)顯表要裝在柜體上，所以要考慮整體的協(xié)調(diào)性，過大了可能裝不下，過小了看不清顯示數(shù)字，另外，體積大的儀表一般功能擴(kuò)充性較強(qiáng)，同樣功能價(jià)格可能會貴，體積小的儀表可能功能擴(kuò)充性較差。目前數(shù)顯表面板的國際標(biāo)準(zhǔn)尺寸主要有以下幾種：48*24mm;48*48mm;48*96mm;72*72mm;96*96mm;96*48mm;160*80mm。</p><p

style="text-indent:25px">數(shù)顯儀表產(chǎn)生干擾的途徑：信號源與儀表之間的導(dǎo)線、內(nèi)部配線通過磁耦合在電路中形成干擾。在大功率變壓器、交流電機(jī)、電力線的周圍空間都存在有很強(qiáng)的交流磁場，而閉合回路處在這種變化的磁場中將產(chǎn)生電動勢。這種感應(yīng)電勢與有用信號串聯(lián)，當(dāng)傳感器與數(shù)顯表距離較遠(yuǎn)時(shí)，這種串模干擾特別突出。干擾源通過電容的耦合在回路中形成干擾，是由于兩電場相互作用的結(jié)果。通過靜電耦合的方式，能在兩輸入端感應(yīng)出對地的共同電壓，以共模干擾的形式出現(xiàn)，由于共模干擾不和信號相疊加，它不直接對儀表產(chǎn)生影響。但它能通過測量系統(tǒng)形成到地的泄漏電流，該泄漏電流通過電阻的耦合就能直接作用于儀表而產(chǎn)生干擾。電磁感應(yīng)、靜電感應(yīng)所形成大多是工頻干擾電壓，但變頻器、帶整流子的電機(jī)等會產(chǎn)生諧波干擾。德陽數(shù)顯儀表</p><p
