External zero adjustment, setting range ±15°
5.7 Autoclaving
Observe the permissible conditions of autoclaving, see chapter
„
9.3 "Permissible temperature"
During the autoclaving process, no weight-loading must be exert-
„
ed via the case and the instrument must not lie on its window.
After the first autoclaving cycles, the window slightly arches
„
outward. This has no effect on the function of the instrument.
Depending on the autoclaving process, whitish residues can build
„
up on the window and pointer. This has no effect on the function of
the instrument.
In case of a zero offset, carry out a zero adjustment. See chapter
„
5.6 "Zero adjustment".

The zero adjustment can be made
with a slotted screwdriver after the
removal of the sealing plug on the
top of the case.
Deviations in the display due to
natural fluctuations in the atmos-
pheric pressure and altitude varia-
tions (up to 2,000 m height above
sea level) can be compensated
with the zero adjustment.
