the keys adjacent to the arrow icons to increase or decrease the selected number. Standard values
from 0.001 to 1000 can be entered. The standard value can be reset to one by pressing the key

A standard value should only be entered if the factor is not known. If the factor is known the standard
value should be set to 1.000.
