Measure (G Dataflow)

Last Modified: August 30, 2018

Returns the measured value of either the voltage or current on the specified output channel.

Each call to this node blocks other node calls until the hardware returns the measurement.

connector_pane_image
datatype_icon

session in

Instrument session obtained from the Initialize With Channels node.

datatype_icon

channel name

Output channel to measure.

Multiple Measurement Channels or Types

Only one measurement at a time may be made with the Measure node. Use the Measure Multiple node to measure multiple channels or measurement types.

datatype_icon

measurement type

Input that specifies whether to measure a voltage or current value.

Name Value Description
Voltage 1 The power supply or SMU measures voltage.
Current 0 The power supply or SMU measures current.

Default: Voltage (1)

datatype_icon

error in

Error conditions that occur before this node runs.

The node responds to this input according to standard error behavior.

Standard Error Behavior

Many nodes provide an error in input and an error out output so that the node can respond to and communicate errors that occur while code is running. The value of error in specifies whether an error occurred before the node runs. Most nodes respond to values of error in in a standard, predictable way.

error in does not contain an error error in contains an error
If no error occurred before the node runs, the node begins execution normally.

If no error occurs while the node runs, it returns no error. If an error does occur while the node runs, it returns that error information as error out.

If an error occurred before the node runs, the node does not execute. Instead, it returns the error in value as error out.

Default: No error

datatype_icon

session out

Handle used to identify the session in all subsequent NI-DCPower node calls.

datatype_icon

measurement

Value of the measurement, either in volts for voltage or amps for current.

datatype_icon

error out

Error information.

The node produces this output according to standard error behavior.

Measuring Multiple Output Channels

To measure multiple output channels, use the Measure Multiple node.

Where This Node Can Run:

Desktop OS: Windows

FPGA: Not supported

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