c) Push pressure sensor with pressure sensor board to the
rear until stopper.
d) Move lower slide of the finger pump rearwards.
e) Note down pressure sensor value.
f) Insert 4 mm calibration gauge.
g) Push pressure sensor with pressure sensor board slightly
forward.
h) Tighten screw (2).
The measured value read on the pressure sensor must be
5 to 15 digits above the value noted.
Note
Pull nut slightly out of the pressure sensor housing.
i) After calibration return to the initial function with END.
j) Select SAVE NO. (Do not actuate the YES key.)

pump cover and let snap in at the locking bow.
f) Position weight 1 (100 g) for 400 mbar carefully in the
holder on the pressure sensor. The weight must be placed
without any friction in the holder.
g) Note down measured value.
h) Repeat steps f) and g) with weight 2 (128 g) for 800 mbar
and weight 3 (166 g) for 1200 mbar.
