Sensor selection F1 / F2 

With this parameter, you can define the sensor 
type. Depending on the hardware, not all sensor 
types may be supported. For the NTC sensor, a 
parallel resistor will have to be connected.

 Software filter F1 / F2 

In this parameter, you can define how many meas-
ured values are to be used for calculating a mean 
value. A mean value is calculated from the last 
measured values, with the oldest measured value 
being deleted (so called "Moving Average Filter").

you can define via this parameter which value is to 
be displayed in the case of a current of 0 or 4mA or 
a voltage of 0V. The value to be displayed for 
20mA/10V can be defined in the next parameter. 
The actual measured value is calculated as linear 
interpolation between these two values.

 Intern: active data set 

With this parameter, you can set up pre-defined 
data sets. The data sets are provided by Störk-
Tronic. If a new data set is loaded, all previously set 
parameters will be overwritten. After that, they can 
be edited as required. The most important settings 
are shown in the appendix. Basically the different 
refrigerants are configured.
