5.
Write the resulting waveform to AO and start the task.
6.
Measure the output voltage with the DMM.
7.
Stop the task.
8.
Compare the result with the limits in
Note
Before proceeding to the next channel, call DAQmx Channel
Property Node, and set the AO Idle Output Behavior property
(Analog Output>>General Properties>>Output Configuration>>Idle
Output Behavior) to Zero Volts. This will avoid any damage to the
device that may be caused by removing cables while the output is
active.
