Calculation of differential value/mean value

The differential value and mean value connection interfaces have the following special

features compared to the standard interface:

Setting start of scale value and end of scale value:

● Firstly enter the start of scale value and end of scale value for both individual sensors.

● Then assign the parameters for the start of scale value and end of scale value for the

Sensor calibration:

● Trim the sensor to the respective measuring range limits for the two individual sensors.

8.10

You can set the filter time constant of electrical damping to a point within a range from 0 to

30 s.

8.11

You can use this function to switch the transmitter into constant current mode for test

purposes. In that case, the output current no longer corresponds to the process variable.

Operating Instructions, 04/2007, A5E01071992-01

The start of scale value and end of scale value are thus the same for both sensors. You

cannot parameterize different measuring ranges for individual sensors. Tip: Use the

largest measuring range.

differential value and mean value measurement.

The differential value and mean value set in the parameters cannot be trimmed.
