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:

•

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).

•

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

,

 function).

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.
