Calibration
values of the height differences
achieved with the first and the
second measurement are equal,
and the instrument operates error-
free. In case the height differences
are not equal, the instrument has to
be adjusted according to the
following procedure:

Care and storage

1. Use a soft cloth to clean
instrument from dust and dirt.
2. Carefully clean lens and ocular
with a soft and clean cloth, cotton or
a soft brush, use no liquids other
than pure alcohol. Do not touch any
surfaces of the lenses.

2. Adjustment
Calculate the value
b2soll = a2 - a1 + b1
and adjust the cros-
shairs, with the aid
of the calibration
screws, which are
visible behind the

by turning screw 3 until b2 = b2soll.
After that, carefully tighten
calibration screws against each
other.
b) In case b2 is larger than b2soll,
loosen screw 3 and adjust crosshairs
by operating screw 1 until B2 =
b2soll. After that, carefully tighten
calibration screws against each
other.
Repeat control of the adjustment
until you get the result(a1 - b1) =
(a2 - b2), then replace lens cap.
The calibration screws 2 and 4 are
for calibration sideways and are
normally not to be used.
Formula:

b = a -a +b

b = a -(a -b )

3. After use under wet weather
conditions, container and instrument
are to be field-cleaned and then, at
home, left to dry thoroughly with the
container open.
4. For carrying the instrument over
long distances, it is best to place it in
its container. Attention: Levelling
screws to be turned all the way in.
