Install this meter and log a building’s energy for a period of time for example an hour, a week, or one month to get all the data you need.
This handheld three-phase power quality analyser uses external Rogowski coils and voltage-sensing clamps. The flexible Rogowski coils are very easy to install, unlike large CTs. The coils can easily be opened and closed, so no need to disconnect any wires. The voltage-sensing clamps can easily be clamped on, so no need to switch off power. In other words, the meter can easily be installed without any power interruptions.

This meter comes with 3 x 600A (36mm diameter) rogowski current sensing coils. If you would like to measure larger currents or larger bus bars, order the following rogowski coils additionally.

Yes, it comes with 4 voltage sensing leads. 3 Current sensing coils, that can measure up to 600A, and a USB power supply and cable. If you want to measure higher currents, then you have to buy larger Rogowski coils, also available here.
According to the manual only 7 hours, but in our experience the batteries last up to 48 hours (Rechargeable 2500 mAh Duracell). When logging longer periods of time it is recommended to use a USB power supply and connect it to the USB C power supply port on the meter. Alternatively one could also use a large USB power bank, just make sure it is large enough to last the duration you want to log for. A 10 0000 mAh Power bank will last 3 days in our experience.
The amount of space required for one day’s logging at 1-minute intervals is 1 kB. So, on a 4 GB SD card, one can log for more than 8 years.
At ten-second intervals, it will be, six times more data, that will work out to about 4.5 MB per day. So, one will be able to log for about 1.3 years on a 4GB SD card.
Each meter is factory-tested and calibrated. The allowable variance is less than 0.02% Click here to see an example 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.
If you are using CTs then use the ratio specified on the CT, however, if you are using Rogowski coils then there is no ratio to be set. You can set the option to use CTs or the Rogowski coils under “Wire settings” in the menu, then “iCon” (Current Connection). So use “CTCon” for CTs and “RCoilCon” for Rogowski coils.
It is possible that your loads can generate negative reactive energy. Read this article on Wikipedia.
The maximum size that can be used with the meter is 32 GB, please ensure the SD card size is 32 GB or smaller. Also, the SD card must be formatted with the FAT 32 file system. Please format the SD card on your computer with the FAT 32 File system.
No, the meter needs to have power supplied to it’s USB C port, either by a USB power supply or a USB Powerbank. If no USB power is connected, then it will stop working as soon as its internal batteries are flat, after about 72 hours.
For this reason, we also sell USB Powerbanks that are large enough to last for more than 7 days. https://greenenergysolutions.co.za/power-banks/
The current value may not be displayed if the duration that the current flows, is below 1 second. The current is still measured and taken into account for the energy consumption. So if the current flows for very short periods of time, then it will not be recorded. The overall energy usage will still be recorded accurately
Another reason is if the 3000A coil is used, and the current flow is less than 3A, then it can not be measured.
It seems that there might be an error in the wiring configuration. Please confirm if it is set to 3-phase 4-wire (3PH4W).

Overall product rating:
Great product, it does what it should. The coils are really easy to install.
Does as advertised. Very useful.
The product arrived in a timely fashion and we immediately put it to work to monitor power usage for a client.
It has been very helpful for us to determine the maximum loads for commercial clients to install backup and solar systems.
5 Stars, would recommend to anyone.
Power supply.
Hi, I tested the product and the results are good for what is am looking for. it is only the battery lifetime that is a problem.
Some of my sites need more time measuring.
Hi Gert. Thank you for your review. The 4 x AA batteries only last 48 hours, if you need more time, please supply the meter with power from a plug in USB power supply or an external power bank.
