Great device, mediocre software
I’ve used Amprobe devices since the late 90’s – my first exposure being the DM-II. As always the devices are great; however, the software could use some updating. It looks pretty much the same as it did in 1997. It’s glitchy to install and the UI is dated. We often take readings for engineering firms looking to capture data. They don’t like that they need to install the full software suite to analyze the file and would like a small file viewing application.
✔ Yes, I recommend this product.

We’re sorry to hear your tool did not meet your expectations. The DM-III is no longer being supported as we have released the new DM-5 Power Quality Analyzer as a replacement.
