①消(xiao)除安全(quan)隱患(huan)，增加安全(quan)系(xi)數②③消(xiao)除靜電儀器本身消(xiao)除2外界干(gan)擾米的空間，當(dang)現(xian)場變頻(pin)如何解決？

①帶獨立變頻電(dian)源的(de)(de)(de)功率計，以避免(mian)與不同②儀器(qi)的(de)(de)(de)在房間內的(de)(de)(de)驅動(dong)的(de)(de)(de)干擾功率，以避免(mian)空間干擾米(mi)③電(dian)纜的(de)(de)(de)良好的(de)(de)(de)接地(di)電(dian)線屏(ping)蔽必須連(lian)接④選定(ding)的(de)(de)(de)輸出端口(kou)應屏(ping)蔽電(dian)纜如何檢測時(shi)好時(shi)接地(di)3，加電(dian)無顯(xian)示儀表？

①功率儀表面板②存在(zai)或不存在(zai)所述(shu)輸入交流(liu)(liu)電壓檢測儀器的主(zhu)板，電源板，以(yi)查看(kan)是(shi)否直流(liu)(liu)電壓輸出③面板打開，看(kan)插座(zuo)是(shi)否就座(zuo)4，如何選擇安(an)裝點(dian)？

直管的①選擇填充有液體。

②測(ce)量點應該(gai)上游10D，下游5D被定位，沒有干(gan)擾(rao)閥(fa)。

③保證動作(zuo)溫度(du)范圍(wei)內的(de)測量點。

④選擇管(guan)均勻且(qie)致密的，易于傳(chuan)輸超聲波管(guan)部。

⑤避(bi)免泵(beng)，高功率(lv)無線電，磁場干擾(rao)，振(zhen)動計(ji)的安(an)裝位置。

如圖6所示(shi)，那些具(ju)有(you)表輸(shu)出？

①RS232連接器(qi)(qi)②③電流回路的輸出(chu)頻率輸出(chu)7，在使用方法(fa)Z什(shen)么(me)(me)條(tiao)件下分兩步安裝器(qi)(qi)械常用的方法(fa)V，什(shen)么(me)(me)樣的條(tiao)件下？

①V法：適用于較小的直徑一般d<250mm②Z法：適用于較大管徑，一般D>典型地，該250mm③，V是(shi)安裝(zhuang)的標準方法(fa)，或當管是(shi)很厚(hou)，由于液體懸(xuan)浮液的存在，嚴(yan)重結垢壁(bi)太厚(hou)或襯墊，導致V法(fa)不能(neng)正常(chang)工(gong)作(zuo)，選擇的安裝(zhuang)方法(fa)?。

8，固定和(he)便攜式雷(lei)達液位計具有標(biao)準？

固定①：主機，傳感(gan)器(qi)，兩根繩子，卡扣4中，兩種硅氧(yang)烷，兩個彈簧中，說明。

便攜式②：主機(ji)，充電(dian)(dian)(dian)電(dian)(dian)(dian)纜傳感器(qi)(qi)，傳感器(qi)(qi)保(bao)持器(qi)(qi)是固定的，電(dian)(dian)(dian)力線，一(yi)個適配器(qi)(qi)，兩個鋼鏈(lian)，兩個彈簧，一(yi)個描(miao)述，一(yi)卷紙(zhi)。

如(ru)圖9所示(shi)，在安(an)裝傳感器時，器械被始終檢測(ce)到的狀態(tai)，如(ru)何(he)檢測(ce)？

①檢(jian)(jian)查(cha)參數設置是否正確(que)；②檢(jian)(jian)查(cha)電(dian)纜(lan)而不斷裂；③檢(jian)(jian)查(cha)傳感器接(jie)線是否正確(que)；④檢(jian)(jian)查(cha)是否在(zai)管(guan)中(zhong)的流(liu)體；⑤縮放所(suo)述壁(bi)太厚或者如(ru)果(guo)襯(chen)里(li)不緊密，重新調試切換點。
