JDZ-A电子水平仪是一种测量微小倾角的高精度仪器。它主要用于测量被测表面相对于水平面的倾角及表面的直线度、平面度。例:精密平板的平面度,精密机床和精密仪器导轨的直线度、扭曲度,以及设备和仪器的安装水平位置。与普通水平仪相比,具有精度高、读数方便,并能作远距离测量。主要技术指标如下。分度值:Ⅰ型1角秒、Ⅱ型2角秒;示值误差:不超过±1最小分度值;整机零点飘移:4小时不超过一个最小分度值;重复精度不超过1/5分度值;灵敏度0.3角秒;读数前指针稳定时间
JDZ-A electronic level meter is a kind of high precision instrument for measuring small inclination. It is mainly used to measure the inclination of the measured surface relative to the horizontal plane and the straightness and flatness of the surface. Example: Flatness of precision plates, straightness, twist of precision machine tools and precision instrument guides, and installation level of equipment and instruments. Compared with the ordinary level, with high precision, easy reading, and for long-distance measurements. The main technical indicators are as follows. Dividing value: Ⅰ type 1 arc second, Ⅱ type 2 arc seconds; Indication error: not more than ± 1 minimum scale value; Whole machine zero drift: 4 hours does not exceed a minimum scale value; Repeatability does not exceed 1 / 5 divisions; sensitivity 0.3 arc second; pointer stabilization time before reading
