‘Automatic’
‘Menu / Information

Settings
è
Automatic

...’
In the
‘Automatic’
menu, you can set whether the unit is to meter automat‐
ically or conventionally.
With
‘Automatic’
-
‘on’
you set direct values, such as capacity, metering
volume or dosing time instead of stroke length and stroke rate. The other
selection points will also appear in the operating menu - refer to the
chapter "Operating Menu for gamma/ X, complete" (in the appendix) for
the selection points highlighted with a "*1".
In
‘Automatic’
-
‘on’
metering mode, the gamma/ X specifies the stroke
length and the stroke rate according to the conditions determined in order
to meter the set capacity.
‘Automatic’ - ‘on’ and ‘Automatic’ - ‘off’ metering modes
are completely independent of each other. That is the say
that the ‘Automatic’ - ‘off’ does not carry over settings from
‘Automatic’ - ‘on’ .
