Output format
If only manufacturer scaling via the feature register is active, the output format is as follows:
- 1 digit corresponds to 1/10 °C or
- 1 digit corresponds to 1/10 Ω
If no scaling is active, the output format is as follows:
- 1 digit corresponds to 1/16 °C or
- 1 digit corresponds to 1/16 Ω
If the Siemens output format is selected, the lowest three bits are used for status evaluation. The process data is represented in bits 3 to 15, with bit 15 representing the sign bit. Scaling of the measurement reading according to the Siemens standard has to be done via user scaling.

• R33: User scaling - offset (B_w)
16 bit signed integer
This register contains the offset of the user straight-line equation (1.6). The straight-line equation is activated via register R32.
• R34: User scaling (A_w)
16 bits signed integer* 2-8.
This register contains the scaling factor of the user straight-line equation (1.6). The straight-line equation is activated via register R32.
• R35 and R36: reserved
• R37: Filter constant
