Connect the Voltage Monitor to the power supply that you want to
measure.
Indication of the voltage:
Depending on the value of the supply voltage detected, the LEDs 4-6, as shown in
the table opposite.
Indication of the frequency value:
Depending on the value of power frequency detected, the LEDs 1 to 3, as shown in the tables below. Voltage Monitor can work in two different
ranges of values of frequency around 50 Hz and about 60 Hz The device automatically sets the range at power up.
