交通(tong)標線逆反射測量儀使(shi)用方法
交通標線逆(ni)反射測(ce)量儀(yi)電源充電
在使(shi)用(yong)標線(xian)測量(liang)儀測量(liang)路面標線(xian)前,首先要為(wei)儀器(qi)(qi)中的(de)電池充(chong)(chong)電。充(chong)(chong)電時將充(chong)(chong)電器(qi)(qi)插頭插入充(chong)(chong)電插座(7)內,然后將充(chong)(chong)電器(qi)(qi)的(de)輸(shu)入導線(xian)插頭插入市電(交流220V)電源上(shang),充(chong)(chong)電器(qi)(qi)上(shang)亮起(qi)的(de)指示(shi)燈(deng)含義為(wei):紅燈(deng)亮表(biao)示(shi)正在充(chong)(chong)電,綠燈(deng)亮表(biao)示(shi)充(chong)(chong)電完成(cheng)。
儀器調零
當充(chong)電完成后(hou),將電源開(kai)(kai)關(6)按下,即(ji)電源接通,這時顯(xian)示(shi)(shi)器(qi)有數(shu)字顯(xian)示(shi)(shi)。儀器(qi)調(diao)(diao)零(ling)前,先將儀器(qi)底部開(kai)(kai)口(kou)(300mm×60mm)對準(zhun)放在黑色調(diao)(diao)零(ling)板(ban)上,并按下測量(liang)開(kai)(kai)關(4),這時在測量(liang)值(zhi)顯(xian)示(shi)(shi)屏(1)上顯(xian)示(shi)(shi)值(zhi)應為0;如果不為0,則轉動調(diao)(diao)零(ling)旋鈕(2)直至使顯(xian)示(shi)(shi)值(zhi)為0,此時表(biao)示(shi)(shi)調(diao)(diao)零(ling)完畢(bi)。
交通標(biao)線逆反射(she)測量儀(yi)儀(yi)器校準
調(diao)(diao)零以后,將黑(hei)色調(diao)(diao)零板(ban)(ban)去掉,按行(xing)車箭頭方向(校(xiao)(xiao)準(zhun)板(ban)(ban)上有標記)換上校(xiao)(xiao)準(zhun)板(ban)(ban),此(ci)時測量值顯(xian)示屏(ping)(1)上顯(xian)示值應為校(xiao)(xiao)準(zhun)板(ban)(ban)給(gei)定的值;如(ru)果(guo)與給(gei)定值不相符,則轉動(dong)校(xiao)(xiao)準(zhun)旋鈕(3)直至使(shi)顯(xian)示值為校(xiao)(xiao)準(zhun)板(ban)(ban)給(gei)定值,此(ci)時表示校(xiao)(xiao)準(zhun)完畢(bi)。
4.標線測量
儀器(qi)調零和(he)校準完成后,即可進行測(ce)(ce)(ce)量(liang),測(ce)(ce)(ce)量(liang)時(shi)應將儀器(qi)按行車(che)方向平(ping)放在(zai)被(bei)測(ce)(ce)(ce)標(biao)(biao)線(xian)上(shang),按下測(ce)(ce)(ce)量(liang)開關(guan)(guan)(4),預熱l分(fen)鐘,在(zai)測(ce)(ce)(ce)值(zhi)顯(xian)示(shi)器(qi)(1)顯(xian)示(shi)穩定(ding)數(shu)(shu)值(zhi),即為(wei)被(bei)測(ce)(ce)(ce)標(biao)(biao)線(xian)的逆反射系數(shu)(shu)值(zhi)(R’),記錄數(shu)(shu)據后及時(shi)關(guan)(guan)閉測(ce)(ce)(ce)量(liang)開關(guan)(guan)(4)。所有測(ce)(ce)(ce)量(liang)完畢后,將電源開關(guan)(guan)(6)關(guan)(guan)閉。
友情提示:在(zai)現場測(ce)量(liang)標線(xian)時,為了防止儀(yi)器(qi)底部(bu)與(yu)路面(mian)接觸(chu)部(bu)位(wei)外界(jie)雜光的進(jin)入(ru),可以用深色毛巾(jin)等(deng)在(zai)儀(yi)器(qi)底部(bu)圍擋遮光。以保證測(ce)量(liang)數(shu)值穩(wen)定(ding)準(zhun)確。
