If the concentration scale is set to “Auto Scale,” the software determines
the minimum and maximum concentration values for the current average
interval. To select a
concentration range, select either the “Min”, “Max” or
the “Min/Max” radio button. The box below “Min Concentration”, “Max
Concentration” or both will become enabled and you may enter a value,
where the Minimum Concentration is equal to or greater than zero and less
than the Maximum Concentration.
To change the scale between log and linear mode, press the
