    Nice tidy meter and easy to wire in, although I had to contact technical support for clarification because the printed instructions and the wiring diagram on the device itself do not match. Tip: Follow the diagram in the sheet, not on the unit. Part of me wanted to try it both ways to test; the other part of me did not want to risk releasing the smoke-fairies. A quick call to tech support put me right.

    I bought the DIN enclosure, but didn’t need it as I had a spare way in my garage consumer unit. No matter as it will get used at some point soon.

    This meter has a soft green backlight which makes it very easy to read without needing a torch. Nice touch.

    The barn on the side of my house which contains my business office and workshop now has a way of recording electricity consumption, This will make sorting out business and household consumption a lot easier for me.

    It not only does what it says on the tin, but really looks the part in my installation. I just wish I had a couple of these ten years ago when I still had power-hungry teenagers in the house!
