Can be switched on or off; the gain and offset values
cannot be changed.
When user scaling is switched on, the user can enter
values for offset and gain.
The register values can be represented and edited as
either decimals or hexadecimals. If the user scaling is
deactivated, the offset and gain values cannot be
changed.
Offset The offset value causes a zero offset of the
process value (shift along the Y axis). The
value entered must fall within the range −32768
to 32767.
Gain The gain value is used as a gain factor applied
to the process value.
The value entered must fall within the range
−2.0000 to 1.9999.
The resolution 1/16384 has already been taken
into account for the decimal entry.
The process value can be constant or deliberately kept
changeable;
it can be represented as a fixed decimal value with unit
or as a hexadecimal to correspond with the
measurement range.
