Adjustment
Empty and full adjustment via the spindle potentio-
meter. The integrated slide clutch avoids overwin-
ding.
Before either adjustment each potentiometer must
be turned by approx. 22 turns clockwise.
In practice 3 versions are possible to carry out the
empty / full adjustment.
a) The level can be set to the required min. level
(= 0%) and max. level (= 100 %)
Empty adjustment
• Set level to the required min. level.
• Adjust the indication of the instrument to 0 % by
the potentiometer for empty adjustment.
Full adjustment
• Set level to the required max. level.
• Adjust the indication of the instrument to 100 %
by the potentiometer for full adjustment.
b) The level in the vessel can be set to the
required min. level (= 0 %), but only to a max.
level < 100 %
Empty adjustment
• Set level to the required min. level.
• Adjust the indication of the instrument to 0 % by
the potentiometer for empty adjustment.
Full adjustment
• Set product to the highest level and check with
dip measure (e.g. 80 %).
• Adjust the indication of the instrument to the
checked value (in the example 80 %) with the
potentiometer for full adjustment.
c) The level in the vessel can be only set to a
min. level of > 0 % and a max. level ≤ 100 %
VEGAMET 307 / 308
Empty adjustment
• Set product to the low level and check with dip
measure (e.g. 20 %)
• Set indication of the instrument to 0 % with the
potentiometer for empty adjustment.
Full adjustment
• Set level to highest possible level and check with
dip measure (e.g. 60 %).
• Calculate the indicated value to be adjusted:
highest level minus lowest level = indicated value
to be adjusted.
In the example: 60 % – 20 % = 40 %.
• Set indication of the instrument to the calculated
value (in the example 40 %) with potentiometer
for full adjustment.
• Set the indication of the instrument to the actual
level (highest level, in the example 60 %) with
the potentiometer for empty adjustment.
