Digital multimeter is designed to monitor the current and voltage values of the threephase operating loads.When the device is energized, firstly you need to enter the current transformer value in order to see the current values accurately.You can set the current transformer value by entering the menu. If you make direct connection without current transformer under 5A, you need to ensure that the current transformer value is 5.The device shows the phase-neutral, phase-phase voltages, frequency, phase sequence and current values.
