Example: 5-ring resistors are: red, yellow, red, black, gold, reading is 242Ω

The error is ±0.5%
Example: 5-ring resistors are: orange, white, yellow, red, silver, reading is 39400Ω=39.4K

The error is ±10%
Example: The 5-ring resistors are orange, orange, red, gold, and red. Orange, orange, and red are 332Ω, multiplied by 0.1 = 33.2Ω

The error is ±2%

From the above, we know that we must be careful when reading the fourth color ring as gold or silver, because it is a negative number of multiplication.

Regarding the error rate: The error rate of this software must be multiplied by 100. For example, if the calculated error value is 0.02, multiply it by 100 = 2%
