Units Of The Pulse Function; Analogue Signal Types - INTEGRA Metering CALEC energy master Installation And Operating Instructions Manual

22.4.6 Units of the pulse function

The unit of the output pulse value depends on the unit of the corresponding meter. If, for instance, an energy
meter reading in kWh is connected with a pulse output signal, the unit of the pulse value is Wh/pulse. The table
shows the relationships:
