Description
Pulse width 20-1000 ms
100 ms
The actual pulse width is a multiple of
the 1/2-cycle time rounded to the
nearest bigger value.
The pause time between pulses is equal
to the pulse width.

Links a pulse relay to the internal
energy pulse source. The relay must be
set into either pulse, or KYZ mode.

Generating Energy Pulses through Relay Outputs
To generate energy pulses through a relay output:
Set a relay to either pulse, or KYZ mode, and then select a polarity (active pulse
edge) for energy pulses and a pulse width.
Select a source accumulator (type of energy) and the pulse rate for your output.
Store your new setup to the device.

Programming Analog Inputs
The PowerSmart+ Advanced PQM can be provided with two optional analog inputs
with options for 0-1mA, ±1mA, 0-20mA or 4-20mA input currents, depending on the
order. The 0-1mA and ±1mA inputs can accept 100% overload currents, i.e., can
actually measure currents in the range of 0-2 mA and ±2mA.
The meter automatically converts the analog input readings received from the
analog-to-digital converter to the user-defined engineering scale and shows the
input values in true engineering units, for example, in volts, amps, degrees, with the
desired resolution.
To configure the Analog Inputs in your device, select General Setup from the Meter
Setup menu, then click on the Analog Inputs tab. If you are programming your
device online, analog inputs are designated as not available if they are not present
in the device.
The available options are described in the following table.
