、概述

zui高標準設計和制造的KTZLC-40A變壓器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(quan)措施(shi)

1使(shi)用本儀器(qi)前定要認(ren)真閱讀本手冊(ce)。

2儀器的(de)操作者應具備(bei)(bei)般電氣設備(bei)(bei)或儀器的(de)使用(yong)常識。

3本儀(yi)器戶(hu)內外均可使(shi)用(yong)，但應(ying)避開雨(yu)淋、腐蝕氣體(ti)(ti)、塵埃(ai)過濃、高溫、陽(yang)光直射等場所(suo)。

4儀表應避免劇烈振動。

5對儀器的維(wei)修、護理和調(diao)整應由專業(ye)人員進行。

6測(ce)試(shi)完畢后定(ding)要等放電(dian)報警(jing)聲停止(zhi)后再關閉(bi)電(dian)源，拆除測(ce)試(shi)線(xian)。

7測量無載調壓變壓器，定要等放(fang)電指示報警(jing)音停止后(hou)，切換(huan)檔(dang)位。

8在測(ce)試過程中，禁止移動測(ce)試夾和供電線路。

三(san)、性能特點

1儀器(qi)輸出(chu)電流大，測量范圍寬(kuan)，體(ti)積小，重(zhong)量輕。

2電流輸出根據所(suo)測阻值的大小(xiao)自動調整電流，使之跳到(dao)合(he)適的量程內，避免了電流選擇(ze)不當引起的錯誤。

3具(ju)有完善的(de)保護電路，可靠(kao)性(xing)強。

4立式機(ji)箱結構，便(bian)于現場操(cao)作(zuo)。

5具有(you)音響放電(dian)報警，放電(dian)指示清晰，減少誤操作。
