The microprocessor of the ZxQ reads the digital raw data from the output
buffer of the signal processor every 0.2 seconds.
Based on the digital raw data provided by the signal processor, the
microprocessor calculates the measured quantities listed in the tables
below.
Depending on the functional range of the meter (energy C.4, netenergy C.6
or enerflex C.8), different sets of measured quantities are available.
Availability
Meters for three-phase, three-wire networks (F-circuit) are not yet
available.
With energy (C.4) the following measured quantities are available:
Measured quantity
Active energy import
Active energy export
Reactive energy import
Reactive energy export
Reactive energy in quadrant I
Reactive energy in quadrant II
Reactive energy in quadrant III
Reactive energy in quadrant IV
Phase voltages (RMS)
Phase currents (RMS)
Network frequency
Phase angle between voltages
Phase angle between voltage and current
Direction of rotating field
Phase failure
* Phase angles will only be displayed if voltage L1 is present.
** Phase angles will only be displayed if all voltages are present.
