逆反射系数测量仪使用方法(fa)：
1、电(dian)源充电(dian)
在(zai)使用标(biao)线测(ce)量(liang)仪测(ce)量(liang)路面标(biao)线前(qian)，首先(xian)要(yao)为仪器(qi)中的(de)(de)电(dian)(dian)(dian)(dian)(dian)池充电(dian)(dian)(dian)(dian)(dian)。充电(dian)(dian)(dian)(dian)(dian)前(qian)先(xian)将功(gong)能转换开关(6)置(zhi)于充电(dian)(dian)(dian)(dian)(dian)位置(zhi)，将充电(dian)(dian)(dian)(dian)(dian)器(qi)插(cha)头插(cha)入充电(dian)(dian)(dian)(dian)(dian)器(qi)插(cha)孔(7)内，然后(hou)将充电(dian)(dian)(dian)(dian)(dian)器(qi)的(de)(de)输入导(dao)线插(cha)头插(cha)入市电(dian)(dian)(dian)(dian)(dian)(交流220V)电(dian)(dian)(dian)(dian)(dian)源上，充电(dian)(dian)(dian)(dian)(dian)器(qi)上亮(liang)起的(de)(de)指示灯含义为：红灯亮(liang)表示正在(zai)充电(dian)(dian)(dian)(dian)(dian)，绿(lv)灯亮(liang)表示充电(dian)(dian)(dian)(dian)(dian)完成(cheng)。
2、仪器调零(ling)
当充(chong)电完成后(hou)，将转换开关(guan)(6)置(zhi)于测(ce)量位置(zhi)，按下测(ce)量开关(guan)(4)，预热l分钟，这时(shi)显(xian)(xian)示器有数字(zi)显(xian)(xian)示。仪(yi)器调(diao)零(ling)前(qian)，先将仪(yi)器底部开口(300mm×60mm)对准放在黑(hei)色调(diao)零(ling)板上(shang)，并按下测(ce)量开关(guan)(4)，这时(shi)在测(ce)量值显(xian)(xian)示屏(1)上(shang)显(xian)(xian)示值应为(wei)0;如果(guo)不为(wei)0，则转动调(diao)零(ling)旋钮(2)直至使显(xian)(xian)示值为(wei)0，此时(shi)表(biao)示调(diao)零(ling)完毕。
3、仪(yi)器校准
调零以(yi)后，将黑色(se)调零板(ban)去(qu)掉，按行车箭头方向(校(xiao)准板(ban)上(shang)有标记)换上(shang)校(xiao)准板(ban)，此时测量值(zhi)(zhi)显(xian)示屏(1)上(shang)显(xian)示值(zhi)(zhi)应为校(xiao)准板(ban)给定的值(zhi)(zhi);如果与给定值(zhi)(zhi)不(bu)相符，则转动校(xiao)准旋(xuan)钮(3)直至(zhi)使显(xian)示值(zhi)(zhi)为校(xiao)准板(ban)给定值(zhi)(zhi)，此时表示校(xiao)准完毕。
4. 标线测量
仪器(qi)调零(ling)和校准完成(cheng)后，即可进行测(ce)量，测(ce)量时(shi)应将仪器(qi)按行车方向平放在被测(ce)标线上，在测(ce)值显示器(qi)(1)显示数值即为被测(ce)标线的(de)逆反射系数值(R’)，记(ji)录(lu)数据后及时(shi)关闭测(ce)量开关(4)。所有测(ce)量完毕后，将功能转换开关(6)置(zhi)于(yu)中(zhong)间(jian)位(wei)置(zhi)。
友(you)情提示：在现场测(ce)量(liang)(liang)时，为了防止仪器(qi)底部与路面(mian)标线接触部位外界杂光(guang)的进入，可(ke)以(yi)用(yong)(yong)深色(se)毛(mao)巾等在仪器(qi)底部围挡遮光(guang)。以(yi)保证测(ce)量(liang)(liang)数值(zhi)稳定准(zhun)(zhun)确(que)。测(ce)量(liang)(liang)白色(se)标线时用(yong)(yong)白色(se)校(xiao)(xiao)准(zhun)(zhun)板校(xiao)(xiao)准(zhun)(zhun)，测(ce)量(liang)(liang)黄(huang)(huang)色(se)标线时用(yong)(yong)黄(huang)(huang)色(se)校(xiao)(xiao)准(zhun)(zhun)板校(xiao)(xiao)准(zhun)(zhun)，二者不可(ke)混用(yong)(yong)。
