So why not buy a good meter?Ĭheaper meters will try to impress you with all sorts of features and gimmicks, but nobody quite makes a meter like Fluke. Fluke has led the market for half a century and a lot of their products are iterations on great ideas. What I am trying to say is that the DMM field is mature and it doesn't advance that much. Oscilloscopes become outdated, new DSOs will have more gigasamples and more memory in the future, but for the most part even 30 year old digital hand held multimeters are still pretty good.įurthermore unlike the Oscilloscopes you can get a pretty top notch Fluke multimeter for 100-300 dollars, so does it make sense to skimp on something that you will own and use for the rest of your life? If you need to watch really fast signals, you should be doing that with a logic analyzer or an oscilloscope anyway.Ī good multimeter is absolutely worth it! When it comes to electronics never is the phrase "you get what you pay for" more true than with multimeters. If you need to measure capacitors, inductors, are panicky about your duty cycle, or need tight accuracy, or you need the thing to survive falling down a waterfall or being inside crazy EMF fields or your'e gonna beat the thing up, I'd look for a Fluke or something. Really, to solve all those problems, a $5USD digital multimeter does all that and more. What is the duty cycle of the PWM signal? (This is easily found by doing a little bit of math based on the voltage). ![]()
