6.5 Resistance limitation (r-control)
.
Function
If the current resistance measurement exceeds the resistance limit value, the
power output is limited via the amplitude control.
Resistance limitation is used in the operation of molybdenum disilicide heating
elements to avoid overheating in the upper temperature range. By measuring
the resistance of the heating element, it is possible to assign a precise heating
element temperature and it is therefore protected against overheating.
This only works for load resistances with a positive temperature coefficient.
