Review on Sperry Instruments DM6410 Yellow Digital Multimeter – 8 Function, 600V AC/1000V DC: Reliable and Accurate Electrical Testing Tool by Christopher Holker

This is my big meter. I use it for repairing larger equipment and for AC tuning. I dictate the setting I use and it hasn't let me down. It's got a big screen for that old blind technician to see. This counter travels in a tool backpack and has withstood rough treatment. I take it out to use an average of 10 times a day and it gives accurate readings every time. All of my Sperry counters deserve a mention.
