style="text-indent:25px">測量速率數(shù)字萬用表每秒鐘對被測電量的測量次數(shù)叫測量速率，其單位是“次/s”。它主要取決于 A/D 轉(zhuǎn)換器的轉(zhuǎn)換速率。有的手持式數(shù)字萬用表用測量周期來表示測量的快慢。完成一次測量過程所需要的時間叫測量周期。測量速率與準(zhǔn)確度指標(biāo)存在著矛盾，通常是準(zhǔn)確度愈高，萬用表測量速率愈低，二者難以兼顧。解決這一矛盾可在同一塊萬用表設(shè)置不同的顯示位數(shù)或設(shè)置測量速度轉(zhuǎn)換開關(guān)：增設(shè)快速測量檔，該檔用于測量速率較快的 A/D 轉(zhuǎn)換器；通過降低顯示位數(shù)來大幅度提高測量速率，此法應(yīng)用的比較普通，可滿足不同用戶對測量速率的需要。輸入阻抗測量電壓時，儀表應(yīng)具有很高的輸入阻抗，這樣在測量過程中從被測電路中吸取的電流極少，不會影響被測電路或信號源的工作狀態(tài)，能夠減少測量誤差。測量電流時，儀表應(yīng)該具有很低的輸入阻抗，這樣接入被測電路后，陜西袖珍萬用表，陜西袖珍萬用表，可盡量減小儀表對被測電路的影響，但是在使用萬用表電流檔時，陜西袖珍萬用表，由于輸入阻抗較小，所以較容易燒壞儀表，請用戶在使用時注意。進(jìn)口萬用表多少錢一臺？陜西袖珍萬用表</p><div

style="text-indent:25px">3、測量元件參數(shù)。對故障范圍內(nèi)的元件，進(jìn)行在線測量或離線測量，應(yīng)分析參數(shù)值。對于電阻在線測量時，應(yīng)考慮與其并聯(lián)的元件的影響。4、隱性故障排除。隱性故障是指故障時隱時現(xiàn)，儀表時好時壞的故障。此類故障比較復(fù)雜，常見的原因包括焊點虛焊，松脫、接插件松動，轉(zhuǎn)接開關(guān)接觸不良，元件性能不穩(wěn)，引線將斷不斷等。此外，還包括一些外界因素所造成的。如環(huán)境溫度過高，濕度過大或附近有間歇性的強(qiáng)干擾信號等等。5、檢測各級工作電壓。檢測各點工作電壓，并與正常值比較，萬用表（圖19）首先應(yīng)保證基準(zhǔn)電壓的準(zhǔn)確度，比較好是使用一塊相同型號或相近似的數(shù)字萬用表進(jìn)行測量、比較。排除以上可能原因外，數(shù)字萬用表損壞還有可能是因為測量檔位的錯誤造成，如在測量交流市電時，測量檔位選擇置于電阻擋，這種情況下表筆一旦接觸市電，瞬間即可造成萬用表內(nèi)部元件損壞。因此，在使用萬用表測量前一定要先檢查測量檔位是否正確。在使用完畢，將測量選擇置于交流750V或者直流1000V處，這樣在下次測量時無論誤測什么參數(shù)，都不會引起數(shù)字萬用表損壞。陜西袖珍萬用表4位半數(shù)字萬用表那個品牌好？</p><div
