A summary of the interactions between RAM and EEPROM.
The basic status of the analyzer (factory settings) can be reestablished using the function
"Load Factory Settings" (function 75).

You can use this function to define the response of the analog output with certain alarms. The
response for fault (S), transmission alarm (TR), for start-up, function control (CTRL) and
transmission pending can be defined independently.

Analog Output To: 3/1 mA
You can use this function to set to one of the following modes:
- default. This value has been set in the previous screen.
- the latest measured value before the error occured
- 3/1 mA. (3 mA if the NAMUR mode is active for the analog output in screen 70, and 1 mA
otherwise)
- off. This setting is used to ignore the current fault state for this error group. The
analyzer continues to show the latest measured value.
Use soft key 1 to switch between the different modes.
When an alarm occurs and the analog output is set to the latest measured value or 3/1 mA, the
display of the concentration value in the measuring screen will be suppressed.
