e.g: When "V" LED is turned on:
„ Device is in phase-neutral voltage menu.
„ Line-1 phase-neutral voltage is monitored in the first display.
„ Line-2 phase-neutral voltage is monitored in the second display.
„ Line-3 phase-neutral voltage is monitored in the third display.
„ Average phase-neutral voltage of three phase is monitored in fourth display.
„ Network frequency is monitored in fifth display.

Cosφ and reactive power for the L1 phase is capacitive, otherwise is inductive.
Cosφ and reactive power for the L2 phase is capacitive, otherwise is inductive.
Cosφ and reactive power for the L3 phase is capacitive, otherwise is inductive.
Total reactive power is capacitive, otherwise is inductive.
