DAQmxAdjust1520Cal

int32 DAQmxAdjust1520Cal (uInt32 calHandle, float64 refVoltage, float64 measOutput);

Purpose

Adjusts the external calibration constants for the SCXI-1520 module. You must supply a known voltage to the device and specify that voltage with refVoltage.

This device needs 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.

Parameters

Input
Name	Type	Description
calHandle	uInt32	A reference to the calibration session that you created using the DAQmxInitExtCal function.
refVoltage	float64	The known voltage, in volts, to use as a reference for calibration.
measOutput	float64	The voltage measured at the output of the module.

Return Value

Name	Type	Description
status	int32	The error code returned by the function in the event of an error or warning. A value of 0 indicates success. A positive value indicates a warning. A negative value indicates an error.
