Energy Measurement with Pulses
➭
Set the
triG cont in
parameter in the EVENTS counter for
example at 999 mV, see chapter 22.2.1.
➭
Select energy measurement with pulses in the EnErGY
menu by setting the following parameters:
3 V measuring range:
The internal power source of the multi-
meter (1 mA/max. 3 V) leads to a measured signal level
Low < Value
triG cont in
if there is a short circuit in the mea-
suring circuit. This trigger level is exceeded again when the
measuring circuit is open. The pulse signals can thus be
generated via a switching contact.
30 V measuring range (for S0 pulse):
The internal power
source is deactivated in this setting. For the active voltage
pulses which are connected (e.g. 0/24 V
) the same
trigger level
triG cont in
applies for High/Low detection.
Other parameters to be configured:
pulse/kWh ratio, unit of mea-
sure W, VA or VAr for mean and maximum values as well as
the corresponding integral-action time (see chapter 20.3).
➭
Set the selector switch to “
”.
➭
Press the
ESC|FUNC
key twice.
Active power measurement has now been activated.
Each additional activation of the
ESC|FUNC
key causes
switching to the various display functions for energy

,
mean value

, and maximum power values
MAX VA
and

Connect the pulse output (for example from a meter) to
the “
⊥
” and “V” jacks.
