7、空计检定规程本规程适用于新制造、使用中和修理后的压阻真空计的检定。一概述压阻真空计由规管、测量显示单元和连接电缆组成。测量显示单元有指针式和数字式两种类型。规管为压阻应变式传感器。工作时，压阻应变片变形输出电信号，经测量显示单元转换成相应的压力值，其值由数字显示或指针指示出来。压阻真空计标称测量范围为105--1护Pa,测量范围为1护一1护Pa.二技术要求1外观1.1压阻真空计测量显示单元应有产品名称、型号、编号、制造单位和出厂日期等标志。规管应有型号和编号等标志。1.2测量显示单元的功能键应能正常工作;连接

8、电缆应完好。1.3指针式测量显示单元不应有机械零点失调、卡针和表面刻度不清楚等现象。1.4数字式测量显示单元应无缺字、缺段、数字乱跳等现象。1.5规管的接插件应无松动。2绝缘电阻压阻真空计的电源端子对机壳的绝缘电阻，应不低于20Mno3压力示值相对误差在压力测量范围1护一1护Pa内(包括1护，1护Pa点)，示值相对误差不超过士20%。三检定条件(一)检定设备4二等标准真空装置1套:压力范围为1护一1
