s:05aaaaabcd s:05
Get
i:05 i:05aaaaabcd
data length 8 characters
a Value
00001…99999 (10000 = 1.0000)
b Sign Exponent
0 = “-“, 1 = “+”
c Exponent
0…4
d Pressure Unit
0 = Pa
1 = bar
2 = mbar
3 = ubar
4 = Torr
5 = mTorr
6 = atm
7 = psi

SENSOR 1
LINEARIZATION
Set
s:17aaaabbbb s:17
Get
i:17 i:17aaaabbbb
data length 8 characters
a logarithmic resolution[ millivolt /decade]
0000 = linearizing off
0001 = min. value
9999 = max. value
(default value: 0000 = linearizing off)
b full scale [millivolt]
0001 = min. value
9999 = max. value
(default value in logarithmic mode: 5324 = 5.324V)
(becomes linear full scale = 1000000)
Pressure control algorithm adaptive downstream needs a linear sensor signal, therefore a
logarithmic signal must be linearized.
Example: s:1700000000 = Linear sensor
Example: s:1810007800 = Logarithmic sensor (1.0V/decade, Linear full scale at 7.8V)
