These state-of-the-art panel meters are designed for
accurate measurement of the AC RMS voltage, AC
RMS current, frequency, active power and power
factor in single-phase systems. The current
transformer ratio can be set between 5/5A and
5000/5A via front panel buttons.
Devices have separate inputs for supply and
measurement.
The unit allows both manual selection of the display
channel and automatic scrolling.
Changing Display Selection:
By using the MENU button, voltage, current,
active power, power factor and frequency can be
selected and read from display. Every depression on

Do not open the unit. There is no serviceable parts
inside.
Fuses must be connected to the power supply and
phase voltage inputs, in close proximity of the unit.
