Operating modes

The Multi-Channel Controller can be set to one of the following operating 
modes:

Measurement mode

The measurement mode is the standard operating mode. It displays the pres-
sure readings of the transmitters. In case of an error, a status message is dis-
played instead. See Chapter 4.4 Measurement mode, 

27.

Parameter mode

The parameter mode gives you access to various parameters. You can check 
the parameter settings or modify them using the arrow buttons. This allows 
you to configure the Multi-Channel Controller. See Chapter 4.5 Parameter 
mode, 

33.

Program transfer mode

The program transfer mode is used to transfer the latest version of the firm-
ware to the Multi-Channel Controller. See Chapter 7.2 Program transfer 
mode, 

85.

4.4

Measurement mode

4.4.1

Selection

The Multi-Channel Controller automatically selects the measurement mode 
after it has been switched on.

When the unit is set to the parameter mode, it will automatically return to the 
measurement mode if no button is pressed for 10 seconds.
