📎TX PULSE LED

Installing the optical read head on the meter

Installing the optical read head

Indicator light

Locate the flashing diode on the meter. It is on this diode that the optical reader will be positioned. The optical read head can only interpret LED flashes with a flashing duration of 3ms minimum and 100ms maximum.

Viewfinder attachment

Clean the meter around the flashing diode. Glue the viewfinder by aiming the diode through the hole (the viewfinder has adhesive)

Drive lock

Clip the reader into the viewfinder. Exert a uniform force over the entire surface of the sensor.

Checking

Once you power your transmitter, the red LED will light up periodically for 20 seconds, then the green LED will take over.

Consumption calculation

The pulse optical reader records 1 pulse every 5 flashes.

Calculation formula = (A x 5) x B x C x D

A = Number of pulses measured

B = Pulse weight Blue tariff: 0.1W/pulse. In this case, enter 0.1 for B value in the calculation below. Other tariffs: Shown on the meter’s interface (label or screen)

C = TC ratio (Current transformation) Blue tariff: 1

Yellow tariff: 20, 40 or 100 (shown on the meter’s interface)

D = TT ratio (Tension transformer)

Blue tariff: 1

Yellow tariff: 1 Green tariff: Shown on the meter’s interface.

The calculation formula above is a calculation of consumption in Watt-hour (Wh). To get a value in Kilowatt-hour (kWh), you just need to divide the value by 1,000
