Configuration testing
After programming the unit, you must test the device to ensure that it performs to your
specifications. This test can be run by varying the level in the application.
I/O Checkout
After the unit is installed, test to verify the wiring.

mA Input
2.6.5. Scaled mA Input Value
Use
trusted external mA source to generate the signal required for testing, and verify the
incoming signal with
expected when the mA level is changed.
mA Output
Use an external device to test the mA output against the measured level. Check that the
mA value changes to reflect the changes in the measured level.
Application test
If you are testing the application by varying the material level, make sure that none of the
control devices are connected (or that at least no power is available to them).
While the level is being cycled, check the results of the discrete inputs either by closing
the circuit externally (preferred) or by using
Input 2
to force the input ON or OFF. Try all possible combinations to thoroughly test the
