DAQmxAdjustDSAAOCal
int32 DAQmxAdjustDSAAOCal (uInt32 calHandle, uInt32 channel, float64 requestedLowVoltage, float64 actualLowVoltage, float64 requestedHighVoltage, float64 actualHighVoltage, float64 gainSetting);
Purpose
Adjusts the external calibration constants for the analog output section of a DSA device. You must use the device to generate a high voltage and low voltage at a specified gain, measure the high and low voltages, then specify the requested high voltage, low voltage, and gain along with the actual high voltage and low voltage.
Parameters
| Input | ||
| Name | Type | Description |
|---|---|---|
| calHandle | uInt32 | A reference to the calibration session that you created using the DAQmxInitExtCal function. |
| channel | uInt32 | The number of the channel to calibrate. This number is the numeric portion of the physical channel name, not the full physical channel name. |
| requestedLowVoltage | float64 | The low voltage you attempted to generate at the gain setting you specified. |
| actualLowVoltage | float64 | The actual low voltage as measured by an external sensor. |
| requestedHighVoltage | float64 | The high voltage you attempted to generate at the gain setting you specified. |
| actualHighVoltage | float64 | The actual high voltage as measured by an external sensor. |
| gainSetting | float64 | The gain setting you used when you attempted to generate the requested high voltage and requested low voltage. |
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. |
