The first count after having connected PULSE-INOUT1 is weighted in relation to the time from the flank for this
counting so that only volume and energy corresponding to the period are counted.
When PULSE-INOUT1 is disconnected, the meter will make a last counting of the verification registers within four
seconds, whereupon counting in the registers stops. The last counting after having disconnected PULSE-INOUT1
is weighted in relation to the time from the previous calculation for the flank, so that only volume and energy
corresponding to this period are counted.
As long as PULSE-INOUT1 is disconnected the values measured during the previous period with PULSE-INOUT1
connected remain in the verification registers.
The verification registers can either be read from the display or via the serial data connection while PULSE-INOUT1
is disconnected:
