1) The highest priority of the device is to record the operating temperature.

2) The highest priority of the device is to record the density via the analog input, as long as the analog input is activated as a density input. If the analog input is not

available as a density input, the system attempts to record the density via the HART input. If both the analog input and the HART input are deactivated as a density

input, the system uses the default density value.

3) The connection via the analog input or HART input is described in the chapter titled „Electrical connections" on page 21.
