I really needed a backlit display, but this one only stays lit for 10 seconds, making it almost unusable for my use. There were no instructions included, but common sense makes it easy to work with. If you're looking for a basic DMM, this one could do the trick very well unless a backlit display is required. I won't be returning it as it works but I need to replace it very soon as I need a backlit display. 3 stars because of the display and the lack of a user manual, otherwise it would be 5 stars. If anyone knows of a site with instructions, please report.
