1. HI 和 LO 输入端子在测量类别 II 条件下(如下所述)连接到电力干线。 2. 电力干线的最大线路电压为 300 VAC。 警告:IEC 测量类别 II 包括通过分支电路上的某一插座连接到电力干线的电气装置。 这些装置包括大多数小家电、测试设备以及插到支路插座上的其他设备。 DM3068 可用于进行这样的测量: HI 和 LO 输入端子连接到这些设备中的电力干线 (最 高 300 VAC) ,或自身连接到支路插座。不过,DM3068 的 HI 和 LO 输入端子不能连 接到永久安装的电气装置中的电力干线,如主断路器配电盘、分配电盘断路盒或永久 连线的电机。这些装置和电路容易出现超过 DM3068 保护极限的过压现象。 注意:高于 300 VAC 的电压只能与电力干线断开的电路中测量。不过,与电力干线断 开的电路中也存在瞬态过电压。DM3068 可以安全地承受高达 2500 Vpk 的偶然瞬态...

RIGOL Measurement Connections DM3068 was designed with many measurement functions and different measurements have different connections. Do not discretionarily switch the measurement function when measuring as it may cause damage to the multimeter. For example, when the test leads are connected to the related current terminals, AC voltage measurement should not be taken.
