The multimeter measures and calculates the current and voltage values of 3 phases as True RMS. It also measures the frequency and displays the measured values on the display. Optionally it can measure neutral-to-earth voltage.
Through the menu, current transformer and voltage transformer settings can be made.
In the models with output feature, it controls the relay output according to the current and voltage value ranges set via the menu.
With the new power supply design, the device does not require a separate supply input. If there is energy in any phase (85-265 Volt) the device can operate.
