How to Use
- Choose 4-band or 5-band mode.
- Select the color bands.
- Calculate resistance and tolerance.
FAQ
What does the tolerance mean?
It shows the expected ± variation around the nominal resistance.
Do you support 6-band?
Not yet. Use 5-band for higher precision; 6th band is usually temperature coefficient.
