This three-phase energy logger is ideal for the following.
- Determining the energy usage/load profile of a building’s energy usage over a period of time.
- Determining a building’s peak power usage.
- Testing the quality of supply for example voltage dips and harmonic analysis, and establishing if voltage levels are in the acceptable range for PV Inverters.
The results from the energy logging can be used for the following.
- Accurately plan solar PV systems, to determine what amount of panels are needed.
- Accurately plan backup power systems, to determine the size of the inverter and battery capacity needed.
- Accurately plan, backup generator size requirements.
- Identify cost-saving opportunities from energy efficiency measures.
- Identify cost-saving opportunities from improving a building’s Power Factor
- Identify cost-saving opportunities from Peak-demand(KVA) requirements (Monitor what is causing high KVA usage and when).
- Monitor and check for phase imbalances to prevent overloading one phase.

Current sensing coils
This meter comes with MRC24 600A Rogowski current sensing coils. If you would like to measure larger currents, or larger bus bars, order the following rogowski coils additionally.
ST08 current clamps
Alternatively you can order the ST08 current clamps. This is idea for measuring small current flows below 1 A, but also up to 10A or 20A.

Calibration Certificate
Here is an example calibration certificate from the German calibration laboratory TüV.
We can also supply a calibration certificate with the meter you buy, at an additional cost. Let us know if this is required when you order.
Frequently Asked Questions
Yes, it comes with 5 voltage sensing leads, 4 current sensing coils, and a USB power supply and cable. The diameter of the current sensing coils is 24mm and it can measure up to 600A, If you want to measure higher currents, then you have to buy larger Rogowski coils, also available here.
The device comes with two 18659 Lithium batteries.
The build in LiPo batteries last 10 hours. We recommend plugin it into mains power if planning to log for longer than 10 hours.
Each meter is factory-tested and calibrated. The allowable variance is less than 0.02% Click here to see an example factory meter calibration report. Additionally each meter can be sent for calibration and receive a calibration certificate at additional cost. Click here to see an example meter calibration report.
The ME440 logs to its data to 31GB internal memory. Then you can then download the data to an USB stick.
No, the meter must be powered by a 5V external power supply, or the internal batteries. One can supply power to the external power supply with this adaptor. Contact us to order this adaptor.
It is possible that your loads can generate negative reactive energy. Read this article on Wikipedia.
The Mi550 has waveform recordings, the sampling rate can be set, Sampling rate (kHz): used to set the sampling rate of waveform, which can be set to 1\2\4\8 kHz, and the corresponding maximum sampling duration is: 40s\20s\10s\5s.
The minimum logging interval of the Mi550 is five seconds. The minimum logging interval of the ME440 and ME435 is one seconds.
The user interface of the meter can be set to any of the following languages:
- English
- German
- Portuguese
- Spanish
- French
- Chinese
If one use the NRC300, it can be configured to have an output of 85mV/kA or 50mV/kA. However, we generally recommend an output of 50mV/kA. The reason is that for a 300mm Rogowski coil like the NRC300, the measured current is usually quite large.
The maximum input voltage range of the Meatrol meters is: 0 – 420mVAC.
When the output of the Rogowski coil is 50mV/kA, the maximum measurable current is 8500A (8,5 kA x 50 mV = 425 mVAC).
But if the coil output is 85mV/kA, the maximum measurable current is 5000A (5 kA x 85mV = 425 mVAC).
The reason why the NRC300 coils comes in 50 mV/kA variation is to accommodate high current readings.

Meter data analysis, visualisation and reporting
We have created an Excel template that can analyse the data and visualise it with graphs. It has the following features and graphs.
- Maximum power per minute, hour and day
- Energy usage per minute, hour and day
- Maximum voltage per minute, hour and day
- Limit data displayed to a specific day or hour
- Supports three-phase and single-phase setups
This template and support with importing the data and using the template are included free of charge when purchasing this meter.
The template is very easy to use even for users that is not that familiar with Excel. We have also created step by step instructions document and video.
