The resistance of the heating circuit is measured directly at terminals and
with an ohmmeter. This resistance can be adjusted by setting the poten-
tiometer P.

The setting accuracy of the resistance value depends on the
quality and measurement deviation of the measuring device
used to measure the resistance value.
