Instruction Manual
2�7 - VERIFICATION PULSES
The device has a combined verification LED used to verify reactive and active energy. The weight of the
LED set to 1,000 imp/kWh(kvarh).
The LED is lit when the current is lower than during the energy meter’s start-up. The LED will turn
off and start emitting impulses proportional to the measured energy when the start-up current is
exceeded (either due to the consumption of active or reactive power), following the rate shown on the
features plate.
This LED has a metallic ring used to fix and help position the verification head.
2�8 - BUTTON
It relies on two keys with a short and long press system. A short press is one lasting less than 2 seconds,
and a long press is one lasting more than 2 seconds. The effect of pressing each key depends on the
version of the meter. One of the keys is sealed to prevent unauthorised personnel from operating the
meter.
2�9 - RATING PLATE
The rating plate is located on the front of the meter and contains the specifications required in IEC
62052-11:
Manufacturer's identification mark and place of manufacture
Type designation and certification markings.
The number of phases and the number of conductors in the circuit to which it can be connected
(e.g., 2-wire single-phase)
Serial number of the meter (9 numeric characters), unique number for each meter.
Year of manufacture, year in which the meter was manufactured.
Reference voltage, in the form of the rated voltage of the mains or the secondary voltage of the
measuring transformer to which the meter is to be connected.
Reference current and maximum current, for example 5(65) A would be a meter with a base
current of 5 A and a maximum current of 65 A.
Reference frequency in Hz.
The energy meter’s constant is based on the active energy impulse ratio, which defines the LED’s
flashing frequency. This ratio is 1,000 impulse/kWh.
Meter class index
The double square symbol
, since the meter has a class-II protective insulating enclosure.
Designation of the number and the arrangement of the measuring elements.
Bar code as per EN 207010 identifying the meter.
Model identifier. Manufacturer's code used to identify the meter model. This code yields its
configuration: power supply, current measurement, measurement system, etc.
Temperature range: - 25 °C to + 70 °C (-40 …+70 ºC metrology).
