Adjusts the external calibration constants for an NI 4220 device.

Namespace: NationalInstruments.DAQmx
Assembly: NationalInstruments.DAQmx (in NationalInstruments.DAQmx.dll) Version: 20.7.40.49302

Syntax

public void Adjust4220(
	string physicalChannels,
	double gain,
	double referenceVoltage
)

Public Sub Adjust4220 ( 
	physicalChannels As String,
	gain As Double,
	referenceVoltage As Double
)

Parameters

physicalChannels: Type: SystemString
The physical channel(s) to calibrate.
gain: Type: SystemDouble
The gain setting to calibrate.
referenceVoltage: Type: SystemDouble
The known voltage, in volts, to use as a reference for calibration.

Exceptions

Exception	Condition
DaqException	The NI-DAQmx driver returned an error.

Remarks

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.
