7.2.19 Saving Data
Data storage takes place during commissioning and maintenance of the device. Current operating pa-
rameters are stored and archived in the LAR database.
Please contact LAR technical support (Chapter 15.1 on page 183) if you need a backup.
7.2.20 Calibrate Analog Output
In principle, it is possible to operate the analogue outputs in the range 0-20 mA or 4-20 mA. The analyser
integrates a "live zero" mechanism via the analogue outputs. This means that 0 mA can be applied to
the current output in case of a device error. Under which conditions this "live zero" mechanism is acti-
vated can be set individually by the user in the selection window. To activate the "live zero" mechanism,
the analogue output must be set to "4/20 mA".
