MIO_Calibrate
Format
status = MIO_Calibrate (deviceNumber, calOP, saveNewCal, EEPROMloc, calRefChan,
DAC0chan, DAC1chan, calRefVolts, refLoc)
Purpose
Note
If you have an E Series device, use
Calibrate_E_Series
.
You can use this function to calibrate your AT-MIO-16F-5, AT-MIO-64F-5, and
AT-MIO-16X devices. You need to calibrate your device under the following conditions:
AT-MIO-16X devices. You need to calibrate your device under the following conditions:
•
If it is operating in an environment with a temperature that differs by more than 10° C
from the temperature at which the device was calibrated. Your device is calibrated at the
factory at room temperature (25° C).
from the temperature at which the device was calibrated. Your device is calibrated at the
factory at room temperature (25° C).
•
Once every year.
You can perform a new calibration or use an existing set of calibration constants by copying
the constants from their storage location in the onboard EEPROM. You also can store
calibration constants. NI-DAQ automatically loads the calibration constants stored in the
EEPROM load area the first time you call a function pertaining to the AT-MIO-16F-5,
AT-MIO-64F-5, or AT-MIO-16X devices that requires calibration constants to be loaded
(when you call an

The load area for the AT-MIO-16F-5 is user area 5. The load area for the AT-MIO-64F-5 and
AT-MIO-16X is user area 8.
AT-MIO-16X is user area 8.
