A resistor value may be entered using the keypad and the corresponding color bands will be displayed on the resistor.
Before entering the resistor value, press the multiplier band and select the correct multiplier for the range of resistor you are looking for.
In the example above the multiplier band is set to red which is the x100 range. You should always pick the lowest range possible to express the value you are looking for.
Once you have selected the multiplier simply type in the resistor value you are looking for.
A single touch on the clear button will delete the last digit. A long press on the clear button will clear the resistor value to zero.
