Harbor Freight Freebie DMM

I suspect every tech may be concerned about slight errors. However, I suspect if I was trouble shooting a ckt my concern would be the voltage difference. Free or not I'm betting if you picked up 20 different digital volt meters there would be errors between them. Back when techs really repaired electronic equipment instead of throw away in todays world we used analog volt meters and calibrated them to flashlight batteries. Didn't seem to handicap the techs. In fact many techs including myself measured DC with a scope which probably had considerable DC error. I have never had a problem trouble shooting an RV problem with a Harbor Freight free meter. I have about 5 or 6 of those free meters. Never had a problem. When was the last time your John Fluke was calibrated? When working in the aero space industry our equipment was calibrated every 30 days on Uncle Sam's dime. Probably a Harbor Freight meter would have worked just fine in the lab without any calibration. :B A meter is only as good as the person holding the probes and reading the meter, calibrated or not. I use the Harbor Freight meters all the time in my RV. Doubt it handicapped my troubleshooting skills. I totally recommend these free meters for every RVer.
