Description
1 = Function is active for this channel.
1 = Scalable measuring range cut off at the over-
flow/underflow of the underlying measuring range.
2 or 3 decimal places
Temperature in whole °C / °F / K

Scalable measuring range active and clipped (clipping)
Resolution: 2 decimal places
Measuring range center: 750 °C
Overflow (Maximum):
250.00 + 750 = 1000.00 °C
Scalable measuring range is clipped at the overflow.
Underflow (Minimum):
-325.12 + 750 = 424.88 °C
