Custom Scaling

To change the module to Fahrenheit you have to convert the equation and set the user registers describe.

Equation:
°F = 9/5 x °C + 32

To set the scaling to 1/10 °F, the constant part (offset) is scaled with 10 multiplied..
This means :

  • for offset 32 *10 =320
  • for the gain (9/5 *10/16 *256) = 288

Necessary register settings:

  • R31 set code word = 0x1235
  • R32 disable custom scaling
  • R32 enable custom scaling
  • R33 custom Offset = 320dez
  • R34 custom Gain = 288dez

Scaling changes are valid immediately and are separate for each channel adjustable.
