I have a resistor in an analog VOM meter that I suspect is bad. It is
exclusive to the 1x ohm scale, which is now reading as if it were the
1000x ohm scale.

The color bands are as follows:

Red
Grey
Violet
Gold
Red

287 / 10 (e.g. 28.7) at 2% tolerance.

I figured that was probably closer to reality so I salvaged up a 100 ohm
and a 39 ohm resistor and put them in parallel to get 28 ohms and the 1x
ohms scale is reading close to normal.


It seems the 5 and 6 band codes are different than the 4.


Here's a correct caclculator:

Or this free app from Schematica.

I'm okay with the normal bands but always screw up the gold/silver
multipliers -- and the tolerance bands? Fuggedaboudit.
