嚴(yan)禁使(shi)用腐蝕性有機溶液擦拭儀器；

2.4  儀器(qi)操作流(liu)程

儀器使用中嚴格按(an)照操作流程進行(xing)

開啟(qi)儀(yi)器電源→接儀(yi)器端測試(shi)線(xian)→接電能表端測試(shi)線(xian)及鉗表→設置校驗(yan)參(can)數→校驗(yan)→拆除(chu)電能表端測試(shi)線(xian)→關閉儀(yi)器→拆除(chu)儀(yi)器端測試(shi)線(xian)。

注：鉗表“+”為電流流進方(fang)向“-”為電流流出方(fang)向。

2.5  接線

校驗單相電能表接線方法:

3、端子充(chong)電(dian)(dian)(dian)線(xian)接上電(dian)(dian)(dian)源，儀器充(chong)電(dian)(dian)(dian)管(guan)理界面(mian)就會顯示電(dian)(dian)(dian)池電(dian)(dian)(dian)壓、充(chong)電(dian)(dian)(dian)電(dian)(dian)(dian)流數值。

如(ru)圖(tu)：

注：當(dang)電(dian)池電(dian)壓值(zhi)達(da)到4.2V表示以為電(dian)池充滿電(dian)

校驗現場充(chong)電

1、在現場校驗界面按【F4】鍵(jian)，界(jie)面會提示“由(you)電池供(gong)電模式換……”

2、當屏幕儀器(qi)儀器(qi)屏右下角供電(dian)模式(shi)標(biao)識為紅色小插頭(tou)圖標(biao)時，儀器(qi)使用校驗現場(chang)電(dian)源供電(dian)模式(shi)并為儀器(qi)電(dian)池(chi)充(chong)電(dian)。

適(shi)配器充電

選(xuan)擇(ze)適配器給儀器電池充電

如圖：

注：在室內校驗臺上使用儀器時，請選擇供電方式為電池或適配器供電，通過電壓端子供電會影響校驗臺的電壓輸出精度或諧波。

2.11  液晶屏(ping)對比度(du)的調整

由于液晶屏本身的技術特性，其對(dui)(dui)比度(du)會隨(sui)環(huan)境溫(wen)(wen)度(du)改變而變化。為適應(ying)不同的工作(zuo)環(huan)境溫(wen)(wen)度(du)，儀器設置了液晶屏對(dui)(dui)比度(du)調(diao)節功能；可以調(diao)整屏幕對(dui)(dui)比度(du)選擇*適合工作(zuo)環(huan)境的*佳顯(xian)示(shi)效果，按【↑】屏幕亮度(du)增大，【↓】屏幕亮度(du)降低。在使用電池供(gong)電時，降低顯(xian)示(shi)亮度(du)會延長(chang)電池供(gong)電時間(jian)。

2.12  字符輸入(ru)、刪除(chu)

輸入字符

進入(ru)(ru)設(she)置(zhi)狀態，把光標移到所需輸(shu)入(ru)(ru)字符(fu)處，按“切(qie)(qie)換”鍵切(qie)(qie)換輸(shu)入(ru)(ru)模式，再按“切(qie)(qie)換”儀器屏幕右下角出現圖(tu)標(biao)為(wei)漢字輸入模(mo)式，出現圖標為小(xiao)寫字母輸入模式，出(chu)現圖標為大(da)寫(xie)字母輸入模式，出現圖標(biao)為阿拉伯數字(zi)(zi)輸(shu)入模(mo)式。在系統(tong)管(guan)理輸(shu)入速度(du)項中有字(zi)(zi)符(fu)輸(shu)入速度(du)設置(zhi)(zhi)功能（詳(xiang)見系統(tong)管(guan)理中輸(shu)入速度(du)設置(zhi)(zhi)說明）。

例(li)：在用(yong)(yong)戶(hu)信(xin)息用(yong)(yong)戶(hu)名輸入“飛達”

把光標移到(dao)用戶信(xin)息(xi)項的用戶名設置項上，按【切(qie)換】鍵，看到(dao)儀器(qi)屏幕(mu)右(you)下角出(chu)現小圖(tu)標即(ji)是(shi)(shi)漢(han)字(zi)輸入模(mo)式，漢(han)字(zi)輸入是(shi)(shi)使用手機常用的T9漢(han)字(zi)輸入法。

使用鍵盤輸入“fei” 器屏幕右下角出(chu)現

通過“←、→”鍵移動(dong)光標到“飛”字上(shang)按【確認】鍵

輸(shu)入“da”

通過“←、→”鍵(jian)移動光(guang)標到“達”字上(shang)按(an)【確認】鍵(jian)

注：當前頁找(zhao)不到自己(ji)需要的漢字可以通過(guo)按“↑、↓”進行翻頁(ye)進行查找(zhao)。儀(yi)器(qi)中的漢(han)字(zi)庫(ku)可進行升級（詳見系統管(guan)理U盤(pan)管理說明）

字符刪除

刪除所(suo)輸入的(de)字(zi)符(fu)，把光標移到所(suo)需要刪除字(zi)符(fu)處，按(an)【F4】鍵進行刪除。

例(li)如：把保存校驗(yan)(yan)數據中(zhong)用(yong)戶信息中(zhong)的校驗(yan)(yan)員(yuan)“飛達”兩個(ge)漢字刪除

通過【←↑→↓】把光標移到“飛達”后，按【F4】鍵刪除。在這種(zhong)狀態下按一(yi)下【F4】 鍵(jian)即刪除一個(ge)文字(zi)。
