智能化交、直流標準電壓、電流校準源 型號：TD-DO30-III+

TD-DO30-III+多功能校準儀是智能化交、直(zhi)流標(biao)(biao)準(zhun)電(dian)(dian)(dian)壓(ya)、電(dian)(dian)(dian)流校(xiao)準(zhun)源。（其中(zhong)(zhong)交流輸(shu)出為真有效(xiao)值顯示(shi)）。采用LCD同時顯示(shi)輸(shu)出實(shi)際值、百分(fen)比和被(bei)檢表(biao)滿度(du)(du)(du)值，可(ke)直(zhi)讀(du)誤(wu)差(cha)。可(ke)設置(zhi)被(bei)檢表(biao)滿度(du)(du)(du)值，并可(ke)根據被(bei)檢表(biao)的刻度(du)(du)(du)選(xuan)(xuan)擇(ze)相(xiang)應(ying)的步進量。 幅值調節可(ke)選(xuan)(xuan)擇(ze)鍵盤(pan)（按鍵）控制(zhi)或(huo)電(dian)(dian)(dian)位器控制(zhi)。具有數(shu)字顯示(shi)、誤(wu)差(cha)直(zhi)讀(du)、量程(cheng)寬、分(fen)檔細、精度(du)(du)(du)高(gao)(gao)、稱定(ding)性(xing)好、使用方(fang)便等(deng)特點。適用于(yu)檢定(ding)、校(xiao)驗修理四位半(ban)數(shu)字三用表(biao)、各種0.2級、0.5級以(yi)下(xia)指(zhi)針式(shi)交、直(zhi)流電(dian)(dian)(dian)壓(ya)、電(dian)(dian)(dian)流表(biao)；亦(yi)可(ke)作為高(gao)(gao)穩定(ding)度(du)(du)(du)測試電(dian)(dian)(dian)源使用，配合高(gao)(gao)等(deng)級標(biao)(biao)準(zhun)表(biao)，校(xiao)對(dui)0.1級電(dian)(dian)(dian)流、電(dian)(dian)(dian)壓(ya)表(biao)。并設有十一檔 ×2中(zhong)(zhong)值電(dian)(dian)(dian)阻。 選(xuan)(xuan)購鉗(qian)型表(biao)標(biao)(biao)準(zhun)線(xian)圈可(ke)以(yi)校(xiao)驗交直(zhi)流鉗(qian)型表(biao)。
