  2. 3458A仪器

  3. 测量功能操作步骤 ____________________________DCV____________________________ a.按蓝色shift+RESET,使仪器恢复到开机的初始设置状态 b.按NPLC,数字键输入 200,并Enter确定,积分计算时间1NPLC设置为200 c.按蓝色shift+N,数字键输入8,并Enter确定,显示精度位数八位半____________________________ACV__________________________ a.按蓝色shift+RESET,使仪器恢复到开机的初始设置状态 b.按ACV,启动交流电压测试功能 c.按蓝色shift+S,并使用方向键选择ACV同步测量2 d.按蓝色shift+R,并使用方向键选择,数字键输入.002,使用仪器的最大分辨率0.002 e.按蓝色shift+L,并使用方向键选择低通滤波3功能

  4. __________________________OHMS____________________________ a.按蓝色shift+RESET,使仪器恢复到开机的初始设置状态 b.按蓝色shift+OHMF,启用4线测量方式 c.按OFFSET COMP启用电阻偏移补偿4功能 d.按蓝色shift+C,并用方向键选择,数字键输入1,使测量延时51秒 e.按NPLC,数字键输入 200,并Enter确定,积分计算时间NPLC设置为200 说明: 1. 长积分计算时间可减少测量噪声及增加测量精度。 2. 同步ACV测量应用的是周期波计算较通常的模拟ACV测量要精确

  5. 3. 低通滤波(≤50kHz)可消除测量干扰。 4. 偏移补偿功能,可减少由电阻发热引起电压偏移而产生的测量误差。 5. 延时测量可减小被测电阻和线缆上吸附的电介质的影响。 蓝色切换键+Menu Keys菜单键允许访问字母所指示的安捷伦3458A的命令和命令参数。使用键可调用A-Z命令和命令参数,使用键可修改命令参数。
