datatype_icon

task in

task in is the name of the task that the operation applies.

datatype_icon

channels

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 node attempts to calibrate all virtual channels in the task.

datatype_icon

shunt resistance

shunt resistance specifies the shunt resistance in ohms.

datatype_icon

shunt element location

shunt element location specifies the location of the shunt resistor.

Name Description
R1

Between Vch- and Vex+.

R2

Between Vch- and Vex-.

R3

Between Vch+ and Vex-.

R4

Between Vch+ and Vex+.

datatype_icon

shunt select

shunt select specifies which shunt calibration switch to enable.

Name Description
A

Switch A.

B

Switch B.

datatype_icon

shunt source

shunt source specifies whether to use an internal or external shunt.

Name Description
Default

Use the default shunt.

Internal

Use an internal shunt.

External Use an external shunt.
datatype_icon

error in

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

datatype_icon

bridge resistance

bridge resistance specifies the bridge resistance in ohms. A value of -1 means to use the nominal bridge resistance specified when you created the virtual channel.

datatype_icon

skip unsupported channels

skip unsupported channels specifies whether or not to skip channels that do not support calibration. If skip unsupported channels is TRUE, this node calibrates only supported channels. If FALSE, this node calibrates the channels specified by channels. The default is FALSE.

datatype_icon

task out

task out is a reference to the task after this node runs.

datatype_icon

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
