EGM-PWM-LAN ENERGY METER WITH LAN INTERFACE
All brands and logos are registered trademarks of their respective owners
This window displays all the measured values:
 Real power (P)
 Active impedance (R)
 Frequency of current (Fq)
 Energy consumed (E)
 The cost of energy consumed (money sign)
 RMS voltage (V rms)
 Peak voltage (V peak)
 RMS current (I rms)
 Peak current (I peak)
It is beyond the scope of this manual to explain the physical meaning
of these values. For most consumers the energy and its cost are the most
interesting.
The Energy (E) value shows the accumulated energy consumption
(in watt-hours) since a certain date (the last time when Reset button was
pressed). This date is shown below the Cost display. The Cost value is
based on the amount of energy consumed and the energy costs. Push
the Set button (near the Cost value) to specify the energy costs for your
home or office situation– see Figure # 17 below.
By Pushing the Reset button both Energy and Cost counters will be
reset to zero.
