6.6.2 Gradient setting by resistance value (WR)
For the MT-ST160WR and MT-ST160WR/RM device versions, set the tem-
perature gradient by adapting the resistance value.
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.
