Instrument configuration
After power-up, the instrument performs a
self-test and then enters the measuring mode.
Now it can be configured and calibrated for
the first time. The values set by the user are
kept even in the event of a power failure.
The following function groups are available on
the Liquisys M (the groups that are only
available on the Plus package are marked
accordingly in the function descriptions):

To help you to select and find function groups
and functions, each function is displayed with
a field designation. The structure of this
designation is given in Fig. 5.2.
The first column indicates the function group
as a letter (see group designations). The
functions in the individual groups are counted
from the top to the bottom and from the left to
the right.

first time, the factory settings are in effect. The
following table provides an overview of all
major settings.
Please refer to the description of the
