当你使用多路用电表时，通常需要按照以下顺序操作：
打开总电源开关：首先，需要确保总电源开关是关闭状态，然后打开它，这将为整个电路提供电源。

打开用电设备：接下来，需要打开你要测量电量的用电设备，例如灯、电视机或冰箱等。

插入电表：将电表插入用电设备和插座之间，确保电表与插座和用电设备之间的连接牢固。

读取电量：在用电设备运行一段时间后，可以读取电表上显示的电量，这可以帮助你计算用电设备的能耗和电费。

关闭用电设备：测试完成后，需要关闭用电设备，以避免浪费能源和产生不必要的费用。

拔出电表：最后，需要拔出电表，以备将来使用。

需要注意的是，操作电表时应谨慎，以避免触电或损坏设备。

在操作前，最好仔细阅读电表的说明书，并遵循相关安全规定。

注意：
1、机械调零时要将红、黑表笔分别插入“+”“-”插孔中。

不管是测量电流、电压还是电阻，测量前都要检查多用电表的指针是否停在表盘刻度线左端的零位置，若不指零，可用小螺丝刀旋转机械调零旋钮(定位螺丝)，直到指针指零为止。

2、测电流时将选择开关拨至电流挡，根据估计电流的大小选取适当的量程。

当电流难以估计时，可先用大量程试测。

注意将电流表串联入待测电路中，让电流从红表笔流入，从黑表笔流出。

3、测电压的过程与此类似，不过要注意将电表并联在待测电路两端，红表笔接高电势，黑表笔接低电势。
