、概述

zui高標準設計和制造的(de)KTZLC-40A直流電阻測試儀采用全新開關電源技術，輸出功率大測試時間超快，所有電流功率器件都采用進口件。公司實行自主研發生產和銷售，杜絕不貼牌。具有體積小、重量輕、輸出電流大并且可根據負載大小自動調整等特點。整機由單片機控制，自動完成自檢、數據處理、顯示、打印等功能，具有自動放電和放電指示功能。

二、安全措(cuo)施(shi)

1. 使用(yong)本儀器前定要(yao)認真閱(yue)讀(du)本手冊。
2. 儀器的操作者應具備般電氣設備或(huo)儀器的使(shi)用常識。
3. 本儀器戶(hu)內外均(jun)可使用，但應避(bi)開雨淋、腐(fu)蝕氣體、塵埃過濃、高溫、陽光直射等場所。
4. 儀表應避免劇烈振(zhen)動。
5. 對儀(yi)器的維修、護理和調整應由專業(ye)人員(yuan)進行。
6. 測試完畢后(hou)定要等放(fang)電報警(jing)聲停(ting)止后(hou)再關閉電源(yuan)，拆(chai)除測試線(xian)。
7. 測(ce)量無載調壓變(bian)壓器，定要(yao)等(deng)放電指示報警(jing)音停止后，切換檔位。
8. 在測試(shi)過程(cheng)中，禁止移動測試(shi)夾和供(gong)電線路。

三、性(xing)能特(te)點

1. 儀器輸出電流大，測量范(fan)圍寬，體積(ji)小，重量輕。
2. 電流輸出(chu)根據所測阻值的大(da)小自動調整(zheng)電流，使之跳到合適的量程內，避免了電流選擇不(bu)當(dang)引起的錯誤。
3. 具有(you)完善的保護電路(lu)，可(ke)靠(kao)性強。
4. 立(li)式(shi)機(ji)箱(xiang)結構，便于現場(chang)操作。
5. 具有音響放電報警，放電指示清晰，減(jian)少誤操(cao)作。
