Pressure Adjustment
By selecting Press (ENTER), it shows the sub-menu:

V_1 V_2
P1 P2
Pressure input adjustment is only completed after calibrating the options:
V_1 , V_2 , P1 and P2 . Note that P1 and P2 refer to two pressure sensors chosen
from P option in CONF menu
The V_1 and V_2 adjustment is performed only at the factory.
The calibrations of the sensors associated to mnemonics P1 and P2 consist of
the application of two pressure values close to zero and full scale (FS) of the
pressure sensor. Store the values of the 1
st
and 2
nd
calibration points by means of
keys 1 (1
st
point) and 2 (2
nd
point).
