Operating instructions

5. Getting started
Before connecting the power cord after unpacking the instrument loosen or remove the three
security screws: remove the backplane in the upper part of the instrument and loosen the
three large screws (marked with red) just right of the pump box (refer to section 15.2 for more
help).
These screws are used as a transportation security only to hold in place the measuring cell
during shipment. For correct operation they must be loosened or removed.
When the instrument is switched on the first time, it is recommended to reset it electronically
to its default values as described in section 10.10 (function 9, memory clear: all parameter).
