心(xin)電(dian)(dian)圖(tu)所稱的(de)(de)(de)電(dian)(dian)壓(ya)，是(shi)指心(xin)電(dian)(dian)圖(tu)紙上兩條橫線之間的(de)(de)(de)距離。常(chang)用來(lai)(lai)測(ce)定心(xin)電(dian)(dian)圖(tu)的(de)(de)(de)波(bo)幅(fu)。單位通(tong)常(chang)用mm或mV來(lai)(lai)表示。電(dian)(dian)壓(ya)的(de)(de)(de)數值與*定準電(dian)(dian)壓(ya)的(de)(de)(de)調節有關。若輸入1mV的(de)(de)(de)標準電(dian)(dian)壓(ya)使基(ji)線上移10mm，潁(ying)泉區耳背(bei)式助聽(ting)器(qi)，則兩條細橫線之間的(de)(de)(de)距離是(shi)1mm，耳背(bei)式助聽(ting)器(qi)哪里有賣(mai)，電(dian)(dian)壓(ya)為(wei)0.1mV。測(ce)量(liang)心(xin)電(dian)(dian)圖(tu)的(de)(de)(de)波(bo)幅(fu)時，電(dian)(dian)壓(ya)定準方有意義(yi)。

電(dian)流(liu)(liu)(liu)(liu)(liu)表(biao)要(yao)與被測用(yong)電(dian)器串(chuan)聯。 [14] 正(zheng)(zheng)(zheng)(zheng)負接線(xian)柱(zhu)(zhu)的(de)接法要(yao)正(zheng)(zheng)(zheng)(zheng)確：使(shi)電(dian)流(liu)(liu)(liu)(liu)(liu)從(cong)正(zheng)(zheng)(zheng)(zheng)接線(xian)柱(zhu)(zhu)流(liu)(liu)(liu)(liu)(liu)入，從(cong)負接線(xian)柱(zhu)(zhu)流(liu)(liu)(liu)(liu)(liu)出，俗(su)稱正(zheng)(zheng)(zheng)(zheng)進負出。 [14] 被測電(dian)流(liu)(liu)(liu)(liu)(liu)不要(yao)超過電(dian)流(liu)(liu)(liu)(liu)(liu)表(biao)的(de)量程。（否則會燒(shao)壞電(dian)流(liu)(liu)(liu)(liu)(liu)表(biao)）可用(yong)試觸的(de)方法確定量程。 [14] 因為電(dian)流(liu)(liu)(liu)(liu)(liu)表(biao)內(nei)阻太小（相當于(yu)導線(xian)），所以不允許不經過用(yong)電(dian)器而把(ba)電(dian)流(liu)(liu)(liu)(liu)(liu)表(biao)直接連到電(dian)源(yuan)的(de)兩極上(shang)。 [14] 確認使(shi)用(yong)的(de)電(dian)流(liu)(liu)(liu)(liu)(liu)表(biao)的(de)量程。 [14]

簡(jian)稱安，用大寫字母A表示。但電(dian)(dian)(dian)流(liu)(liu)強度平(ping)時人(ren)們(men)多(duo)簡(jian)稱電(dian)(dian)(dian)流(liu)(liu)。所以電(dian)(dian)(dian)流(liu)(liu)又代(dai)表一個物(wu)理量，耳背式助聽(ting)器多(duo)少錢(qian)，這是電(dian)(dian)(dian)流(liu)(liu)的第二個含義。電(dian)(dian)(dian)流(liu)(liu)的方(fang)(fang)向(xiang)電(dian)(dian)(dian)流(liu)(liu)的真實方(fang)(fang)向(xiang)和正(zheng)方(fang)(fang)向(xiang)是兩個不同(tong)的概念，不能混淆。習慣上總是把正(zheng)電(dian)(dian)(dian)荷(he)運動的方(fang)(fang)向(xiang)，作為電(dian)(dian)(dian)流(liu)(liu)的方(fang)(fang)向(xiang)，這就是電(dian)(dian)(dian)流(liu)(liu)的實際方(fang)(fang)向(xiang)或真實方(fang)(fang)向(xiang)
