四、使用說明(ming)

1、檔(dang)位(wei)和(he)參數(shu)設(she)置時(shi)，請不要連接(jie)真(zhen)(zhen)空規(gui)管，以防錯誤設(she)置損壞真(zhen)(zhen)空規(gui)管，撥動儀(yi)器(qi)的電源開關(guan)，儀(yi)表電源接(jie)通。

如(ru)果儀(yi)表設(she)置(zhi)在ZJ-51或(huo)者M007規管狀態，顯(xian)示器將(jiang)顯(xian)示-NC-，表示儀(yi)表沒有連(lian)接(jie)上規管。

當(dang)規管和儀表連接(jie)正(zheng)常后，被測量(liang)的(de)真(zhen)空度過量(liang)程時也會顯示HHE。

2、將儀(yi)(yi)表(biao)的插頭線連接到規管上(shang)，液晶屏會顯(xian)示’INIT",表(biao)示儀(yi)(yi)表(biao)初始(shi)化，初始(shi)化成后儀(yi)(yi)表(biao)自動轉入測量狀態，此時儀(yi)(yi)表(biao)顯(xian)示的數值即(ji)為儀(yi)(yi)表(biao)測量到的真空度值。

3、液晶顯(xian)示及介紹

儀(yi)表接上被測系統并(bing)(bing)(bing)檢測到真(zhen)(zhen)空(kong)規管，儀(yi)表會自動(dong)顯(xian)(xian)(xian)(xian)示(shi)測量到的(de)真(zhen)(zhen)空(kong)度(du)值，真(zhen)(zhen)空(kong)度(du)單位(wei)(wei)可以選擇為pa或torr。當(dang)(dang)液(ye)(ye)晶(jing)(jing)屏顯(xian)(xian)(xian)(xian)示(shi)U-PA并(bing)(bing)(bing)顯(xian)(xian)(xian)(xian)示(shi)屏右(you)邊(bian)顯(xian)(xian)(xian)(xian)示(shi)pa，表示(shi)當(dang)(dang)前(qian)(qian)單位(wei)(wei)為帕。當(dang)(dang)液(ye)(ye)晶(jing)(jing)屏顯(xian)(xian)(xian)(xian)示(shi)U-TO并(bing)(bing)(bing)顯(xian)(xian)(xian)(xian)示(shi)屏右(you)邊(bian)顯(xian)(xian)(xian)(xian)示(shi)torr，表示(shi)當(dang)(dang)前(qian)(qian)單位(wei)(wei)為托。當(dang)(dang)液(ye)(ye)晶(jing)(jing)屏顯(xian)(xian)(xian)(xian)示(shi)屏右(you)邊(bian)顯(xian)(xian)(xian)(xian)示(shi)ma表示(shi)當(dang)(dang)前(qian)(qian)顯(xian)(xian)(xian)(xian)示(shi)實(shi)際電流的(de)大小。

4、真空規(gui)管(guan)選擇

（1）按“設(she)置"，顯示(shi)(shi)S-51表示(shi)(shi)選(xuan)(xuan)(xuan)擇(ze)的是ZJ-51規(gui)管(guan)(guan)(guan)，“增(zeng)加"和“減(jian)少(shao)"鍵(jian)可以(yi)選(xuan)(xuan)(xuan)擇(ze)其他(ta)規(gui)管(guan)(guan)(guan)。顯示(shi)(shi)S-07表示(shi)(shi)選(xuan)(xuan)(xuan)擇(ze)的是M007規(gui)管(guan)(guan)(guan)，“增(zeng)加"和“減(jian)少(shao)"鍵(jian)可以(yi)選(xuan)(xuan)(xuan)擇(ze)其他(ta)規(gui)管(guan)(guan)(guan)。顯示(shi)(shi)S-07表示(shi)(shi)選(xuan)(xuan)(xuan)擇(ze)的M007規(gui)管(guan)(guan)(guan)。“增(zeng)加"和“減(jian)少(shao)"鍵(jian)可以(yi)選(xuan)(xuan)(xuan)擇(ze)其他(ta)規(gui)管(guan)(guan)(guan).

（2）、如果選(xuan)(xuan)定(ding)ZJ-51或M007規管，還需要電流(liu)設(she)定(ding)。具(ju)體方法如下：按(an)(an)“設(she)置"。顯示S-51 或則按(an)(an)“增(zeng)(zeng)加"“減(jian)(jian)少(shao)"選(xuan)(xuan)擇(ze)S-07.此時再(zai)按(an)(an)“設(she)置"儀表顯示當(dang)前(qian)設(she)定(ding)的電流(liu)值(zhi)(zhi)(zhi)。并(bing)且電流(liu)值(zhi)(zhi)(zhi)百位(wei)(wei)(wei)數(shu)(shu)(shu)(shu)(shu)值(zhi)(zhi)(zhi)閃(shan)動(dong)，按(an)(an)“增(zeng)(zeng)加"“減(jian)(jian)少(shao)"修改(gai)(gai)百位(wei)(wei)(wei)數(shu)(shu)(shu)(shu)(shu)據(ju)(ju)。修改(gai)(gai)數(shu)(shu)(shu)(shu)(shu)據(ju)(ju)后(hou)按(an)(an)“設(she)置"電流(liu)值(zhi)(zhi)(zhi)十位(wei)(wei)(wei)數(shu)(shu)(shu)(shu)(shu)值(zhi)(zhi)(zhi)閃(shan)動(dong)，按(an)(an)“增(zeng)(zeng)加"“減(jian)(jian)少(shao)"修改(gai)(gai)十位(wei)(wei)(wei)數(shu)(shu)(shu)(shu)(shu)據(ju)(ju)。修改(gai)(gai)數(shu)(shu)(shu)(shu)(shu)據(ju)(ju)后(hou)按(an)(an)“設(she)置"電流(liu)值(zhi)(zhi)(zhi)個位(wei)(wei)(wei)數(shu)(shu)(shu)(shu)(shu)值(zhi)(zhi)(zhi)閃(shan)動(dong)，按(an)(an)“增(zeng)(zeng)加"“減(jian)(jian)少(shao)"修改(gai)(gai)個位(wei)(wei)(wei)數(shu)(shu)(shu)(shu)(shu)據(ju)(ju)。修改(gai)(gai)數(shu)(shu)(shu)(shu)(shu)據(ju)(ju)后(hou)按(an)(an)“設(she)置"電流(liu)值(zhi)(zhi)(zhi)小數(shu)(shu)(shu)(shu)(shu)位(wei)(wei)(wei)數(shu)(shu)(shu)(shu)(shu)值(zhi)(zhi)(zhi)閃(shan)動(dong)，按(an)(an)“增(zeng)(zeng)加"“減(jian)(jian)少(shao)"修改(gai)(gai)小數(shu)(shu)(shu)(shu)(shu)位(wei)(wei)(wei)數(shu)(shu)(shu)(shu)(shu)據(ju)(ju)。修改(gai)(gai)成后(hou)再(zai)按(an)(an)“設(she)置"儀表顯示U-PA表示當(dang)前(qian)單位(wei)(wei)(wei)為帕。按(an)(an)“增(zeng)(zeng)加"“減(jian)(jian)少(shao)"可(ke)以(yi)選(xuan)(xuan)擇(ze)測(ce)量單位(wei)(wei)(wei)。單位(wei)(wei)(wei)修改(gai)(gai)后(hou)按(an)(an)“確認"退出。

（3）在選擇真空規管為(wei)ZJ-51或M007時按(an)“pa/ma"按(an)鍵可顯示當前電流(liu)值。

五、作電源

儀表機內電(dian)(dian)(dian)(dian)池供電(dian)(dian)(dian)(dian)，需用隨機帶的充電(dian)(dian)(dian)(dian)器(qi)(qi)充電(dian)(dian)(dian)(dian)。將充電(dian)(dian)(dian)(dian)器(qi)(qi)插(cha)頭插(cha)入充電(dian)(dian)(dian)(dian)座，充電(dian)(dian)(dian)(dian)器(qi)(qi)上紅燈亮(liang)。當紅燈轉(zhuan)換為綠燈時(shi)。充電(dian)(dian)(dian)(dian)結束，充電(dian)(dian)(dian)(dian)時(shi)間2小時(shi)。充電(dian)(dian)(dian)(dian)后(hou)能作(zuo)10個小時(shi)左(zuo)右。當顯示屏左(zuo)邊“中間字符"閃爍時(shi)提示充電(dian)(dian)(dian)(dian)。為保證儀表正常(chang)作(zuo)及時(shi)充電(dian)(dian)(dian)(dian)。
