5.10.4 Performing a Manual Calibration
To manually calibrate an analog output,
1. Select the desired analog output by clicking
anywhere in the corresponding row.
2. Set the Zero Scale and Full Scale values as
desired.
3. Set the Fixed/Var parameter to “Fixed”.
4. Set Fixed Value equal to the Zero Scale
value.
5. Set Zero Adjustment and Full Adjustment to
“0.0”.
6. Click the button to accept your
changes and exit from the Analog Outputs
dialog.
7. Return to the Analog Outputs dialog. Wait
until the Current Value of the analog output
is equal to the Zero Scale value (see Step 2).
8. Record the value, in engineering units, read
by the receiving device (e.g., a voltmeter).
9. Set Fixed Value equal to the Full Scale
value (see Step 2).
Setting both adjustment values
to “0.0” disables the scale
adjustment.
See Appendix D for an
alternative calibration method
for analog outputs.
Appendix D includes an
example of calibrating an
output scale of 0 to 1200.
