AO Series Calibration
Your device uses software calibration to fine-tune the analog output circuitry. The software must be programmed (or loaded) with certain numbers called calibration constants. Those constants are stored in nonvolatile memory (EEPROM) on your device or are maintained by NI-DAQmx. To achieve specification accuracy, you should self-calibrate your device just before a measurement session but after your computer and the device have been powered on and warmed up for at least 15 minutes. You should allow this same warm-up time before performing any calibration of your system. Frequent calibration produces the most stable and repeatable measurement performance. The device is not harmed in any way if you recalibrate it often.
Static AO devices, such as the NI 6703 and NI 6704, do not self-calibrate or automatically calibrate. You must use a manual procedure to calibrate static AO devices.
Refer to ni.com/calibration for detailed instructions about calibrating your device.

Note Calibrating your AO device takes some time. Do not be alarmed if the Self-Calibrate or Adjust AO Series Calibration function/VI takes several seconds to execute. |

Note For best results, stop any ongoing tasks and disconnect any unnecessary external connections before running calibration. |
Calibration Constant Loading by NI-DAQmx
NI-DAQmx automatically loads calibration constants into the software whenever you call functions/VIs that depend on them.
