Read Calibration ADC (G Dataflow)

Last Modified: July 24, 2019

Takes one or more voltage measurements from the onboard calibration ADC and returns their average value.

The signal that the ADC actually measures can be specified using the Cal ADC Input property. The ADC has some inherent gain and offset. These values can be determined during an external calibration session and stored in the calibration EEPROM.

session in

Handle that identifies your instrument session previously allocated by Initialize External Calibration.

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

number of reads to average

Number of measurements to be taken and averaged to determine the return value.

datatype_icon

return calibrated value

Boolean value that specifies whether or not the voltage returned from the ADC should be adjusted to account for the gain and offset of the ADC.

True The value that is returned from the ADC is adjusted to account for the gain and offset of the ADC.
False The raw voltage value reported by the ADC is returned.
datatype_icon

session out

Reference to your instrument session to wire to the next node.

datatype_icon

error out

Error information.

The node produces this output according to standard error behavior.
