    Note: 1. When current shunt is connected to the negative, set the 20200710114514185.png@!w1600 option to on in the meter menu, see section 6 menu programming interface for details.

    2. When the two current inputs are input by the Hall current sensor, the power supply of the second Hall current sensor cannot be used with the built-in power supply of the meter, and the power module needs to be externally connected.

    3. When the current is input by the shunt, the voltage value measured by the four-wire method has an error of about one thousandth.

    4. It is recommended to use a 0.75mm2 or 1mm2 shielded twisted pair for the current signal line, and the shield layer needs to be connected to the ground.
