Correct Calibration Error
If you receive an error message (Transmitter specific error or Parameter value too large)
(Figure 234), it means that AO is calibrated incorrectly, and the read-back signal is out of
range. And the calibration process is aborted.

The solution is:
1. Click Reset to factory.
2. Redo calibration.
Set Current Generating
The Calibration Tools window also allows you to generate an output current for checking the
current loop and to check 12400 calibration.
To generate output the desired current:
1. Enter the current output value in the Set Current field.
2. Click on Set Current.
Figure 235 Setting Current Output
A dialog appears (Figure 236).
3. Verify that the current output is correct with a precision milliammeter in series with the
AO output.
