DAQmx Adjust 4220 Calibration (G Dataflow)

Last Modified: January 11, 2018

Adjusts the internal and external calibration constants for an NI 4220 device. This device requires reference signals of 0.0 volts at gains of 1, 15, 20, and 310 on a particular channel, in order to perform an offset calibration for that channel. If you do not manually supply those reference signals, the device measures them internally with sample and hold circuitry enabled.


calHandle in

calHandle in is a reference to the calibration session that you created using the DAQmx Initialize External Calibration node.


physical channels

physical channels specifies the physical channel(s) to calibrate.



gain specifies the gain setting to calibrate.


reference voltage

reference voltage specifies in volts the known voltage to use as a reference for calibration.


error in

error in describes error conditions that occur before this node runs. This input provides standard 'error in' functionality.


calHandle out

calHandle out is a reference to the calibration session. Wire this output to other external calibration nodes.


error out

error out contains error information. If error in indicates that an error occurred before this node ran, error out contains the same error information. Otherwise, error out describes the error status that this node produces.

Where This Node Can Run:

Desktop OS: Windows

FPGA: LabVIEW NXG does not support FPGA devices

Web Server: Not supported in VIs that run in a web application
