5 band resistance value query

Hello friends of the forum! Very good to all, I wanted to know if someone in the forum is so kind as to be able to tell me how much the resistance is worth since, being a 5-band, it generates a great doubt. With the multimeter it marks 2.7 ohms. Can it be correct?

I suppose you know the value of the colors of the 4-bar resistors. The first 3 are the 1st and 2nd resistance value, the 3rd multiplier and the 4th bar is the tolerance percentage value. In a 5-band resistor, it is the same as the previous one, only that the first 3 bands are the value, the 4th is the multiplier and the 5th is the% tolerance
in this link you can see the color chart of 4.5 and 6 band resistors

In this there is another that can also serve you

In this link you will get several links with explanations about the bar codes on resistors of 4,5 and 6 colors

You can also get the values of ceramic and tantalum capacitors, ecc ecc. I hope the solution serves you. And by the way already in this forum have asked this question

Before starting the question, I had already used resistance calculators, the point is that everyone in the third band does not appear to choose gold, at least I see it of that color, in addition to putting yellow in the third, in 5th band does not appear the option to mark black.

I started to check in the applications of equivalences of colors and not alle anything like this resistance, so it is best that you measure a low resistance knowing its value to know if the tester is reading well and then read that resistance as long as not This' altered by the use, the truth as I do not find precedents like this case, it would be better to buy a ygual if you get it or try to ask where they sell electronic parts to see if they know what value it is. Check if in the circuit There is more like this. Personally, I think it was the printing press of the colors

luck! if it is not altered, buy one of the value that the tester tells you and install it, I suppose it has to work. It could also be a resistance of pressure and very low resistance, but in that case it would not give so much value. Things are 2 or it is altered or the colors are wrong.
