DAQmx Calibration VIs and Functions
Owning Palette: DAQmx Advanced VIs and Functions
Use the DAQmx Calibration VIs and functions to perform internal and external calibration of devices.
| Palette Object | Description |
|---|---|
| DAQmx Adjust AO-Series Calibration | Adjusts the external calibration constants for an AO Series device. You must connect a known voltage to the device and specify that voltage with reference voltage. |
| DAQmx Adjust E-Series Calibration | Adjusts the external calibration constants for an E Series device. You must connect a known voltage to the device and specify that voltage with reference voltage. |
| DAQmx Adjust M-Series Calibration | Adjusts the external calibration constants for an M Series device. You must connect a known voltage to the device and specify that voltage with reference voltage. |
| DAQmx Adjust SC Baseboard Calibration | Adjusts the external calibration constants for the baseboard of an SC Series device. You must connect a known voltage to the device and specify that voltage with reference voltage. |
| DAQmx Calibration Info Property Node | A Property Node with the DAQmx Calibration Info class preselected. Right-click the Property Node and choose Select Filter from the shortcut menu to make the Property Node show only the properties supported by a particular device installed in the system or supported by all the devices installed in the system. |
| DAQmx Change External Calibration Password | Changes the external calibration password of the device. |
| DAQmx Close External Calibration | Closes an open external calibration session. |
| DAQmx Initialize External Calibration | Starts an external calibration session on a device. |
| DAQmx Perform Bridge Offset Nulling Calibration | Performs a bridge offset nulling calibration on the channels in the task. If the task measures both bridge-based sensors and non-bridge-based sensors, use the channels input to specify the names of the channels that measure bridge-based sensors. |
| DAQmx Perform Shunt Calibration | Performs shunt calibration for the specified channels of the task. The instances of this polymorphic VI correspond to the type of bridge sensor. Refer to the calibration procedure for your module for detailed calibration instructions. |
| DAQmx Restore Last External Calibration Constants | Sets the self calibration constants of the device to the external calibration constants. NI sets the external calibration constants at the factory, and those constants remain in effect until you perform a new external calibration on the device. |
| DAQmx Self Calibrate | Measures the onboard reference voltage of the device and adjusts the self calibration constants to account for any errors caused by short-term fluctuations in the operating environment. When you self calibrate a device, no external signal connections are necessary. |
