"blind setting" greater smaller measuring limit

Zero adjustment Vent transmitter (start of scale remains

(position correction) unaffected). Measuring value in unit of pressure

Current Current Constant output current in mA; 3.6 - 4.0 - 12.0 -

greater smaller   20.0 - 22.8, switched off by "M" key.

Output current in the Selected output current

event of an error Possible: fault current limits set by user  

"0" = none

"LA" = all disable

"LO" = all disable except start of scale

"LS" = all disable except start and full scale

"L" = write protection,

"Lin" = liniar 

"SrLin" = square rooting
