本實用(yong)新型涉及一種(zhong)萬用(yong)表,具體(ti)涉及一種(zhong)短波發(fa)射(she)機電(dian)位器調節專用(yong)萬用(yong)表。
背景技術:
短(duan)波發射(she)機的(de)(de)(de)(de)(de)(de)傳(chuan)動(dong)(dong)部位(wei)(wei)(wei)設置有(you)(you)電(dian)(dian)(dian)位(wei)(wei)(wei)器(qi)(qi),電(dian)(dian)(dian)位(wei)(wei)(wei)器(qi)(qi)的(de)(de)(de)(de)(de)(de)阻(zu)值(zhi)(zhi)準(zhun)確性(xing)能夠提高機器(qi)(qi)的(de)(de)(de)(de)(de)(de)穩(wen)定性(xing),一(yi)般需要(yao)每個(ge)(ge)(ge)月更換(huan)(huan)一(yi)次(ci)電(dian)(dian)(dian)位(wei)(wei)(wei)器(qi)(qi),更換(huan)(huan)電(dian)(dian)(dian)位(wei)(wei)(wei)器(qi)(qi)之前(qian),需要(yao)通過萬(wan)(wan)用(yong)(yong)表將電(dian)(dian)(dian)位(wei)(wei)(wei)器(qi)(qi)的(de)(de)(de)(de)(de)(de)基礎阻(zu)值(zhi)(zhi)設定好(hao),然后(hou)再(zai)安(an)裝在短(duan)波發射(she)機的(de)(de)(de)(de)(de)(de)傳(chuan)動(dong)(dong)部位(wei)(wei)(wei),上機后(hou),由于(yu)固定安(an)裝的(de)(de)(de)(de)(de)(de)過程容易使電(dian)(dian)(dian)位(wei)(wei)(wei)器(qi)(qi)的(de)(de)(de)(de)(de)(de)阻(zu)值(zhi)(zhi)偏離,因此需要(yao)再(zai)通過萬(wan)(wan)用(yong)(yong)表進行(xing)一(yi)次(ci)校準(zhun)調(diao)節(jie)(jie)(jie)(jie)。傳(chuan)統的(de)(de)(de)(de)(de)(de)萬(wan)(wan)用(yong)(yong)表僅(jin)具有(you)(you)電(dian)(dian)(dian)阻(zu)、電(dian)(dian)(dian)壓、電(dian)(dian)(dian)流(liu)測(ce)量(liang)功能,在進行(xing)測(ce)量(liang)工作時,只能通過顯示屏讀數(shu)的(de)(de)(de)(de)(de)(de)方(fang)式來了解測(ce)量(liang)數(shu)值(zhi)(zhi),使用(yong)(yong)不(bu)夠方(fang)便,因此更換(huan)(huan)電(dian)(dian)(dian)位(wei)(wei)(wei)器(qi)(qi)時,往往需要(yao)兩(liang)個(ge)(ge)(ge)人(ren)來進行(xing)操作,一(yi)個(ge)(ge)(ge)人(ren)對拿著表筆接觸(chu)電(dian)(dian)(dian)位(wei)(wei)(wei)器(qi)(qi)的(de)(de)(de)(de)(de)(de)觸(chu)頭(tou),另一(yi)個(ge)(ge)(ge)人(ren)緊盯著萬(wan)(wan)用(yong)(yong)表的(de)(de)(de)(de)(de)(de)屏幕(mu),根據萬(wan)(wan)用(yong)(yong)表屏幕(mu)的(de)(de)(de)(de)(de)(de)顯示值(zhi)(zhi)與(yu)需要(yao)設定值(zhi)(zhi)的(de)(de)(de)(de)(de)(de)差值(zhi)(zhi)來旋轉電(dian)(dian)(dian)位(wei)(wei)(wei)器(qi)(qi)的(de)(de)(de)(de)(de)(de)旋鈕,由于(yu)每個(ge)(ge)(ge)電(dian)(dian)(dian)位(wei)(wei)(wei)器(qi)(qi)要(yao)設定的(de)(de)(de)(de)(de)(de)基礎阻(zu)值(zhi)(zhi)不(bu)一(yi)樣,例如,有(you)(you)的(de)(de)(de)(de)(de)(de)電(dian)(dian)(dian)位(wei)(wei)(wei)器(qi)(qi)要(yao)調(diao)節(jie)(jie)(jie)(jie)到300Ω,有(you)(you)的(de)(de)(de)(de)(de)(de)電(dian)(dian)(dian)位(wei)(wei)(wei)器(qi)(qi)要(yao)調(diao)節(jie)(jie)(jie)(jie)到320Ω,還有(you)(you)的(de)(de)(de)(de)(de)(de)電(dian)(dian)(dian)位(wei)(wei)(wei)器(qi)(qi)需要(yao)調(diao)節(jie)(jie)(jie)(jie)到800歐姆,1400歐姆等等,需要(yao)調(diao)節(jie)(jie)(jie)(jie)的(de)(de)(de)(de)(de)(de)電(dian)(dian)(dian)位(wei)(wei)(wei)器(qi)(qi)數(shu)量(liang)也較多(duo),從而(er)造成電(dian)(dian)(dian)位(wei)(wei)(wei)器(qi)(qi)調(diao)節(jie)(jie)(jie)(jie)更換(huan)(huan)效率低下(xia),影響(xiang)播音效果。
