验证精度测试

下述测试作为测量仪精度测试指南；您的测量仪商店可能会提供特定的测试方法。

危险
HAZARD OF ELECTRIC SHOCK, EXPLOSION, OR ARC FLASH Apply appropriate Personal Protective Equipment (PPE) and follow safe electrical work practices. See NFPA 70E, CSA Z462 or other local standards. Turn off all power supplying this device and the equipment in which it is installed before working on or in the equipment. Always use a properly rated voltage sensing device to confirm that all power is off. Do not exceed the maximum ratings of this device. Verify the device’s power source meets the specifications for your device’s power supply. 未按说明操作将导致人身伤亡等严重后果。

未按说明操作将导致人身伤亡等严重后果。

将测试电压和电流源连接到参考设备或电能标准。请确保所测试的测量仪的所有电压输入均为并行连接，所有电流输入均为串行连接。

使用以下其中一种方法连接用于为标准输出脉冲计数的控制设备：

选项	描述
电能脉冲 LED	将标准测试工作台支架上的红色光传感器对准电能脉冲 LED。
脉冲输出	将测量仪的脉冲输出连接到标准测试工作台的脉冲计数连接。

注: 选择要使用的方法时，请注意，电能脉冲 LED 与脉冲输出的脉冲率限值不同。
