Heating current
Example:
Temperature read: 30°C
Required temperature gradient: 20K
Required display temperature: 30°C + 20K = 50°C
Nominal secondary transformer current: 2.0A
Heating current from setting curve: 1.1A
Setting temperature gradients
ü Make sure that the temperature on the temperature sensor remains con-
stant during the setting process.
ü Open the cover plate.
