Is there a way to put an offset adjustment on the FP-102 soldering iron?

The FP-102 station does not have temperature adjustment or offsetting capability. The station has four heat ranges that provide approximate temperatures of 650ºF, 700º, 750º, and 800ºF depending on the selected heat range setting (Green, Yellow, Blue, or Red). For most tips in the T15 series the measured temperature will be within 50ºF of the selected heat range.
