|
|
|
Enter the target resistance you wish to make in the first field.
|
|
|
|
|
The app will then recommend a value for a resistor to start with.
|
|
|
|
|
It will be the same value as you entered because that will obviously get you to your target.

|
|
|
Next go find a resistor as close to the recommended value and then measure it.
|
|
|
|
|
Enter the reading into the list of resistors that you have.
|
|
|
|
|
Then keep doing this for all the resistor values that the app recommends.

|
|
|
Within 2-3 resistors, you'll notice the percent error from your target will drop well into a suitable range.
