Review on Actron CP7665 AutoAnalyzer Automotive Multimeter by Tim Harris

I think I bought this gauge in 2005-2006 to use on an old Ford 8N tractor with a reconditioned 12v electrical system. PCB design and materials ESP8266/Arduino. Works great there too. I doubt it's calibrated to the level you need for things where it would be very expensive to screw up even a little, but for general DC voltage testing on pin headers and power supplies, checking for shorts after soldering/reworking one Having circuit board or checking AC power in your house wiring is great. The backlit screen is very useful, I don't think I'll ever buy a gauge without this feature.
