The reading of five color ring resistance and the expression of five color ring resistance：

Example: 5 ring resistance in turn: red Huang Hong black gold read 242 ohm. The error is ±0.5%
Example: the 5 ring resistance in turn is orange, white, yellow, red and silver, and the reading error is 39400 =39.4K, the error is ±10%
Example: 5 ring resistance The order is orange orange red gold red, orange orange red is 332 ohm, multiplied by 0.1=33.2 Omega error is±2%
From above, we must pay attention to the fourth color ring as gold or silver, because it is the negative number of multiplication.

About the error rate: the software error rate must be multiplied by 100, such as the number of calculated error shows 0.02 multiplied by 100 = 2%.
