Stored in the memory index values transformer primary current
Ip possible to apply. Choosing the right value compatible with
the values of external transformers automatically sets the cor-
rect ratio, which is calculated according to the actual value of
the collected energy. The LCD displays the actual value of the
energy consumed in the format depending on the selected gear.

The indicator has a pulse output. This allows you to connect a
pulse meter-reading pulses generated by the counter. For proper
operation of the indicator is not required to connect additional
devices.
Constant pulse counter is 12000 pulses/kWh for maximum input
current meter, or the secondary current transformer (5 A). When
using a dedicated transformer the number of pulses per 1 kWh is
calculated from the formula (12000×5)/Ip, where:
Ip – primary current transformer used
Example:
for transformer 5/5 A (Ip=5):
(12000×5)/5=12000 pulses/kWh
for transformer 100/5 A (Ip=100):
(12000×5)/100=600 pulses/kWh
