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.

Use the pull-down menu to select an instance of this VI.

Place on the block diagram.

Find on the Functions palette.

Strain 

Performs shunt calibration for the specified channels using a strain gage sensor.

	task/channels in is the name of the task or a list of virtual channels to which the operation applies. If you provide a list of virtual channels, NI-DAQmx creates a task automatically.
	channels is a subset of virtual channels in the task that you want to calibrate. Use this input if you do not want to calibrate all the channels in the task or if some channels in the task measure non-bridge-based sensors. If the input is empty, this VI attempts to calibrate all virtual channels in the task.
	shunt resistance specifies the shunt resistance in ohms.
	shunt element location specifies the location of the shunt resistor. R1 (12465) Between Vch- and Vex+. R2 (12466) Between Vch- and Vex-. R3 (12467) Between Vch+ and Vex-. R4 (14813) Between Vch+ and Vex+. None (10230) No shunt resistor connected.
	error in describes error conditions that occur before this VI or function runs. The default is no error. If an error occurred before this VI or function runs, the VI or function passes the error in value to error out. If an error occurs while this VI or function runs, the VI or function runs normally and sets its own error status in error out. Use the Simple Error Handler or General Error Handler VIs to display the description of the error code. Use error in and error out to check errors and to specify execution order by wiring error out from one node to error in of the next node. status is TRUE (X) if an error occurred before this VI or function ran or FALSE (checkmark) to indicate a warning or that no error occurred before this VI or function ran. The default is FALSE. code is the error or warning code. The default is 0. If status is TRUE, code is a negative error code. If status is FALSE, code is 0 or a warning code. source identifies where an error occurred. The source string includes the name of the VI that produced the error, what inputs are in error, and how to eliminate the error.
	skip unsupported channels specifies whether or not to skip channels that do not support calibration. If skip unsupported channels is TRUE, this VI calibrates only supported channels. If FALSE, this VI calibrates the channels specified by channels. The default is FALSE.
	task out is a reference to the task after this VI or function runs. If you wired a channel or list of channels to task/channels in, NI-DAQmx creates this task automatically.
	error out contains error information. If error in indicates that an error occurred before this VI or function ran, error out contains the same error information. Otherwise, error out describes the error status that this VI or function produces. Right-click the error out indicator on the front panel and select Explain Error from the shortcut menu for more information about the error. status is TRUE (X) if an error occurred or FALSE (checkmark) to indicate a warning or that no error occurred. code is the error or warning code. If status is TRUE, code is a nonzero error code. If status is FALSE, code is 0 or a warning code. source identifies where and why an error occurred. The source string includes the name of the VI that produced the error, what inputs are in error, and how to eliminate the error.
