Example 1

- Output mode: voltage

- Offset: 0.0

- Gain: 0.1

With the above settings, the analog output voltage range is from 0 V (0

m/s) to 7.5 V (75 m/s). When the measured wind speed is 10 m/s, the

output voltage is 1.0 V. See the formula below:

Output = 0.0 + 10 × 0.1 = 1.0 V

Example 2

- Output mode: current

- Offset: 0.004

- Gain: 0.0002

With the above settings, the analog output current range is from 4 mA

(0 m/s) to 19 mA (75 m/s). When the measured wind speed is 10 m/s, the

output current is 6 mA. See the formula below:

Output = 0.004 + 10 × 0.0002 = 6.0 mA.

Limitations for Output Signals

You can specify the minimum and maximum values for analog output

with the configuration parameters. The output is fixed to the specified

values, and the unit depends on the selected analog output mode.

Example

To limit analog output 1 in voltage mode to a range of 0.1 … 5 V, set the

analog output minimum value to 0.1 and the analog output maximum

value to 5. Enter the following commands:

S aout1minv,0.1

S aout1maxv,5

For more information on the parameters, see Table 18 on page 82.
