Use the DAQmx Calibration VIs and functions to perform internal and external calibration of devices.

DAQmx Self Calibrate VI
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.
DAQmx Perform Bridge Offset Nulling Calibration VI
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 VI
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 Perform Thermocouple Lead Offset Nulling Calibration VI
Performs thermocouple lead offset nulling calibration on the channels in the task to compensate for offsets introduced by open thermocouple detection.
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 Restore Last External Calibration Constants VI
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 Change External Calibration Password VI
Changes the external calibration password of the device.
DAQmx Initialize External Calibration VI
Starts an external calibration session on a device.
DAQmx Close External Calibration VI
Closes an open external calibration session.
DAQmx Adjust 64xx Calibration VI
Adjusts the external calibration constants for a 64xx Series device. You must connect a known voltage to the device and specify that voltage with reference voltage.
DAQmx Adjust E-Series Calibration VI
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 AO-Series Calibration VI
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 S-Series Calibration VI
Adjusts the external calibration constants for an S Series device. You must connect a known voltage to the device and specify that voltage with reference voltage.
DAQmx Adjust M-Series Calibration VI
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 X Series Calibration VI
Adjusts the external calibration constants for an X Series device. You must connect a known voltage to the device and specify that voltage with reference voltage.
DAQmx DSA Calibration
Use the DAQmx DSA Calibration VIs to perform external calibrations of the analog input section, analog output section, and timebase of DSA devices.
DAQmx 42xx Calibration
Use the DAQmx 42xx Calibration VIs to calibrate NI 42xx devices.
DAQmx SCXI Calibration
Use the DAQmx SCXI Calibration VIs to perform external calibrations of SCXI modules.
DAQmx SC Express Calibration
Use the DAQmx SC Express Calibration VIs to perform external calibrations of SC Express devices.
DAQmx C Series Calibration
Use the DAQmx C Series Calibration VIs to perform external calibrations of C Series devices.
DAQmx TIO Calibration
Use the DAQmx TIO Calibration VIs to perform external calibrations of TIO devices.
DAQmx FieldDAQ Calibration
Use the DAQmx FieldDAQ Calibration VIs to perform external calibrations of FieldDAQ devices.
TS Cal
Use these VIs and functions to perform internal and external calibration of NI TestScale devices.
