Y: learn pressure limit according to selected DATA TYPE,
nominal pressure range is 0 ... 10'000 (sensor full scale) but it may be scaled,
refer also to command GAIN for details.
This command transfers/reads the pressure limit for LEARN.
Note: Refer to «LEARN (setup step 5)» for correct learn pressure limit setting.
