Analog output calibration

Flow-X Analog output calibration

The procedure to calibrate an analog output is based on a 4-20 mA meter.

1. Connect the mA meter in series with the load.
2. Go to the analog output calibration display.
Display → Diagnostics, IO, <Module x>, Calibration, Analog outputs
With x the applicable module number, i.e. the flow module to which the signal is physically
connected..
3. Select the channel number of the analog output to be calibrated on the display. This will
adjust the analog output to the 1st calibration point.
4. Increase or decrease the output until it the indication on the mA meter matches the
reference value.
5. Issue the 'Recalibrate this point' command.
Note: recalibration is optional at every calibration point. When the output signal is close
enough to the reference value you may decide to skip re-calibration.
6. Check on the current meter that the output signal corresponds with the reference value
and issue the 'Go to next calibration point' command on the display.
7. Repeat steps 4 through 6 for the remaining calibration points
8. Set the 'Selected analog output' to 'None' or alternatively select the next analog output to
be calibrated. The analog output will now be controlled by the application software again.
9. Disconnect the mA meter.
