How to read the digital counter.

In Spain more and more people have the new digital light meter, which since 2010 is leaving behind the analog counter, the same as always. It is expected to replace it definitively by the beginning of 2019, in the same way that VHS films were changed to DVD. The counter change is completely free.

It is also known as an intelligent meter, because it is able to know exactly the daily consumption, sending the data automatically to the distributor in a precise manner.

What are all the advantages of the digital counter?

  • Goodbye to the estimated readings. Once the telemetry system is integrated, your invoices will be 100% real, you will only pay for what you consume. You can say goodbye to the estimates that many times would suppose an unnecessary extra expense.
  • Effective and fast assistance. When a problem arises at your point of supply, it will be identified and resolved more quickly.
  •  Adjust the power comfortably. If you decide to raise or lower the power you have contracted, you can manage and perform everything remotely.
  • Without cheats. This type of counters are monitored and can not be tricked.
  • Knowledge is power. Thanks to the digitalization, you control your power consumption at any time ahead of your bills. If you know what you are spending, you can reduce consumption and it is much easier to save.

How can I understand the reading?

There is a light that emits the meter, and it is the one that tells you the information of the device. To ensure the type of model you have and how it works, it is best to contact your distributor and provide them with this information. Anyway, let's get a summary to understand the different types of smart meters. The reading will always appear on the screen and the way you read it will be slightly different depending on the rate you have. These data are approximate and may vary according to the counter model.

  • Light off. It usually means that there is no electricity consumption.
  • Fixed red light. Normally it means, that the counter has been blocked since you have exceeded the contracted power. In other cases, there is no consumption, when they have "skipped the leads". If this happens, you see the electrical panel and the differential goes up. In case you want to reset the light meter, you can press the yellow button on the smart meter for a few seconds, or lower the differential.
  • Continuous red light. There is normalized consumption.
  • Flashing light. It means that consumption has skyrocketed.

Rates without time discrimination

2.0A (power> 10 kW) or 2.1A (power 10≥15 kW)

There are several options and you will have to repeatedly press the only button next to it, until you visualize the code 1.81.1 or 1.18.0, and your total consumption in kWh will appear from the beginning of the installation. Therefore, what you will have to do is subtract the consumption that you had from your previous invoice, with the consumption that appears on the screen, which is the current one. We leave you a fictitious invoice so you can visualize it better.


If we subtract the previous reading (total of kWh that appeared in the last invoice) with the current reading (the one that appears on the screen), you will obtain the kWh that you have consumed since your previous invoice was generated.

Rates with time discrimination

2.0DHA (power>10 kW) or 2.1DHA (power 10≥15 kW)

If you have a DHA rate, the consumption of each period will flash alternately on the screen. The peak period reading would correspond to 1.18.1 and that of the valley period to 1.18.2. You will repeat exactly the same thing that we have described previously, but with the consumption corresponding to each period.

3.0A (power <15 kW)

If you have contracted more than 15 kW, the 3 corresponding periods of active energy, reactive energy and maximeter will be measured. To make it easy and not mess with a thousand unnecessary explanations, let's go straight to the point. Look for the codes corresponding to the kWh consumed that will normally be 1.18.1, 1.18.2 and 1.18.3 and do the same subtraction that we did with the rest of the rates for each period.

So far today's explanation, hopefully you have been useful and understand a little more how the digital counter works, taking advantage of this information to have more control of your consumption
