• R20: Manufacturer scaling - gain (A_h)
16 bits signed integer *2
-8
[0x00A0]
This register contains the scaling factor of the manufacturer's straight-line equation (1.5). The straight-line
equation is activated via register R32.
• R21: Additional offset register for two-wire connection
The value of register 1 at short cR1-RL1 or +R2-RL2
[approx. 0x01AX]

User parameters
• R32: Feature register
[0x0106]
The feature register specifies the terminal's operating mode.
Feature bit no.
Description of the operating mode
