Scaling

The settings in the Scaling dialog have a direct impact on the process value.
Scaling is carried out for each channel and is saved permanently, i.e. available
after restarting the node.

Figure 20: Scaling Parameters

To select the process value for the respective channel, select the [Channel
1] ... [Channel (2) 4] radio button.
To display the value in hexadecimal format, select the [hexadecimal] radio
button.
To display the value in decimal format, select the [decimal] radio button.
To switch on manufacturer scaling, select the [Manufacturer scaling] radio
button. When manufacturer scaling is ON, the process value appears scaled in
1/10 °C or Ohm per digit. When manufacturer scaling is OFF, the process value
appears scaled 1/16 °C or Ohm per digit.
For sensor types with ineffective manufacturer scaling (resistance ... 5 kOhm),
the process value appears scaled in 0.5 Ohm per digit.
To switch on user scaling, select the [User scaling] radio button. When user
scaling is ON, the signal charge can be viewed immediately after the
manufacturer scaling. The Offset and Gain fields involve linearization according
to the formula of a linear equation:
f(x) = mx+b
Where:
m = Gain [1/256 per digit, data type: unsigned integer],
