• Pin approx. ш1.3 Ч 50 mm (e.g. a bent open paper clip)
Gauges BPG400-SD, -SP and -SR are mechanically slightly different from the
BPG400. The adjustment opening of BPG400-SD, -SP and -SR is on one side of
the gauge housing. However, the adjustment procedure is the same for all gauge
versions.
Operate gauge for approx. 10 minutes at atmospheric pressure.
If the gauge was operated before in the BA range, a cooling-
down time of approx. 30 minutes is to be expected (gauge tem-
perature = ambient temperature).
Insert the pin through the opening and push the button inside for at least
5 s.

Gauges with display will show the
reading "1000 mbar" and the func-
tion "A" when the button has been
pushed for 4 s. Upon completion of
the adjustment, the function indi-
cation "A" disappears.
The gauge is automatically adjusted ( ≈10 s).
The gauge is now adjusted at atmospheric pressure.
A zero point adjustment is recommended
• after the sensor has been exchanged
• if display shows "FAIL 5" (→ 30)
• as part of the usual maintenance work for quality assurance
