Fct. 3.2.3 TOT ON/OFF TOT. ON/OFF
Select option TOT. ON to start/restart totalizer and select option
TOT.OFF to stop totalizer. Stopping totalizer means flow will not be
accumulated till the time totalizer is turned on again.
Fct. 3.3.0 APPLICAT.
This submenu groups functions which allow you to view/enter the
application data. These functions give the following information to the
instrument.
