Had he said that he was going to be delving into high current tube equipment, the advice would have been different.Īnd since you are involving yourself, perhaps you might want to advise him on the limitations of using his Micronta 22-220A multimeter in said equipment. My suggestion was simply to enlighten him on an inexpensive alternative to having to zero an analog meter, for general usage. Perhaps fine for the car or battery operated transistor radios, but when you are playing with these meters inside tube equipment with higher voltage potentals, the risk to yourself and your level of trust in the multimeter becomes more substantial. But when a company is selling a give away priced multimeter made with the most inexpensive components available, be rest assured it is provided with either bare minimal or no protection from overload. All new digital multimeters can provide measurements. You should always buy the cheapest multimeter you can find, because you know you can always toss it out if you accidentally fry it, and there is always time to upgrade later… right? Food for thought- even one of the most expensive CAT III/IV safety rated DMM’s will be cheaper than the funeral, or even an emergency room visit today. The forum moderator, 7jp4-guy, gave you solid advice, and as for mine, go to Harbor Freight's website and key in multimeter, and you will find several for under five bucks.
