SYNCHRONIZATION OF THE POWER DEMAND CALCU-
LATION
The synchronization enables the WM24-96, by means of the
digital inputs, to start the integration of the power demand
at the same time as the official watthour meter. The syn-
chronization can be carried out in two ways:
- Without digital input module: the reset and the start of the
energy integration are carried out when the instrument is
switched on;
- With the digital input module: the synch. starts when one
of the digital inputs changes status (that is to say when the
tariff changes). Any following change of status resets and
synchronizes again the calculation of the power demand.
