Calibration Circuitry
The X Series analog inputs and outputs have calibration circuitry to correct
gain and offset errors. You can calibrate the device to minimize AI and AO
errors caused by time and temperature drift at run time. No external
circuitry is necessary; an internal reference ensures high accuracy and
stability over time and temperature changes.
Factory-calibration constants are permanently stored in an onboard
EEPROM and cannot be modified. When you self-calibrate the device, as
described in the Device Self-Calibration section of Chapter 1, Getting
Started, software stores new constants in a user-modifiable section of the
EEPROM. To return a device to its initial factory calibration settings,
software can copy the factory-calibration constants to the user-modifiable
section of the EEPROM. Refer to the NI-DAQmx Help or the LabVIEW
Help for more information about using calibration constants.
For a detailed calibration procedure for X Series devices, refer to the
B/E/M/S/X Series Calibration Procedure by clicking Manual Calibration
Procedures on
ni.com/calibration.
