In this video, learn what accuracy is in regards to selecting the right digital multimeter for your needs.
Accuracy, as it pertains to digital multimeters, relates to how closely measurement you’re taking is to the true value of that measurement. Different multimeters will have different levels of accuracy, depending on the capabilities within that multimeters. Higher priced multimeters tend to have higher accuracies because it takes a much more precise circuit to measure things with more precision.
Accuracy is important when selecting a multimeter because you want to have the accuracy of your digital multimeter to be at least four times the accuracy of the measurement you’re taking. The goal is to be times more than the accuracy of the measurement you’re taking.
The Fluke Digital Multimeters are the industry standard for troubleshooting and repair of electrical and electronic systems. Fluke Digital Multimeters (DMM’s) are on more tool belts, finding more problems, than any other comparable test tools. Each design is tested to the extreme: drop, shock, humidity, you name it. Every Fluke Digital Multimeter gives you what you need: accurate measurements, consistent, reliable performance, attention to safety, and the strongest warranty available.

Try to out perform one of the high end Agilent/Keysight hand held meters, they blow the Fluke away, but how important that accuracy is, is a matter of what you are working with.
1% of 10v is 0.1v, and not 1v , how can you take a 1% of 100v and apply it to 10v,!!!!!!!!!????????
👍👍
I don’t understand what the accuracy in multimeter measurements means (fluke 107, for example).
For example, the multimeter indicates an accuracy in measuring volts of 0.5%+3 (in specification)…
The multimeter displayed 3.496 volts on the multimeter screen.
What is the maximum and minimum value of the true value of the measured voltage?
How to calculate the true voltage values (we will denote them by X)?
It can be:
Option 1:
(maximum value): 3.496+0.5%+(0.001*3)=3.51648
(minimum value) 3.496-0.5%-(0.001*3)=3.47552
Option 2 (“+3” is already included in the displayed result):
(maximum value): (3.496-(0.001*3))+0.5%=3.510465
(minimum value) (3.496-(0.001*3))-0.5%=3.475535
Option 3 (error is measured relative to the true value of X):
(maximum value): X-0.5%-(0.001*3)=3.496
(minimum value) X+0.5%+(0.001*3)=3.496
Your option4: =?
Please tell about the formula for measurement accuracy in the specifications for your multimeters!
Fluke = 5 times overpriced
