R33: User scaling – offset
This register contains the offset of the user scaling. User scaling can be activated in the feature register via
bit

R39: Further elements
Register R39 is supported by KL3208-0010 from firmware version 1C and hardware version 01 (Default: 0
dec
)
Setting R39 increases the conversion time to one second per channel
As soon as register R39 is not equal to 0 for one channel of the terminal, the conversion time for all
channels is increased to about 1 second per channel, automatically and irrespective of the sensor
type, in order to optimize the measuring accuracy. The conversion time for all channels can be com-
monly set via register R40 of channel 1. A reduction is not recommended due to loss of accuracy.
