ViStatus niFgen_SelfCal (ViSession vi);
Performs a full internal self-calibration on the device. If the calibration is successful, new calibration data and constants are stored in the onboard EEPROM.

Name | Type | Description |
vi | ViSession | Identifies your instrument session. vi is obtained from the niFgen_init or the niFgen_InitWithOptions functions and identifies a particular instrument session. |
Name | Type | Description |
---|---|---|
status | ViStatus | Returns the status code of this operation. The status code either indicates success or describes an error or warning condition. You can examine the status code from each call to an NI-FGEN function to determine if an error occurred. To obtain a text description of the status code, call the niFgen_error_message function. To obtain additional information about the error condition, call the niFgen_GetError function. To clear the error information from NI-FGEN, call the niFgen_ClearError function. The general meaning of the status code is as follows: |

ViStatus niFgen_GetSelfCalLastDateAndTime (ViSession vi, ViInt32* year, ViInt32* month, ViInt32* day, ViInt32* hour, ViInt32* minute);
Returns the date and time of the last successful self-calibration.
All values are returned as separate parameters. Each parameter is returned as an integer, including the year, month, day, hour, minute, and second. For example, if the device is calibrated in September 2013, this function returns 9 for the month parameter and 2013 for the year parameter.
The time returned is 24-hour (military) local time. For example, if the device was calibrated at 2:30 PM, this function returns 14 for the hours parameter and 30 for the minutes parameter.
