User's Guide ______________________________________________________________________
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 Appendix D,
Configuration Parameters, on page 205.
