void anaLoadCalib();
The A/D Converter Card calibration constants, gain, and offset are stored in the factory in the upper half
of the EEPROM on the A/D Converter Card. Use this function to read the A/D Converter Card calibra-
tion constants, gain, and offset from the upper half of the EEPROM on the A/D Converter Card.

0 if successful.
-1—control command unacceptable.
-2—EEPROM address unacceptable.
The calibration constants may also be saved in the flash memory on the Smart Star CPU Card. Doing so
will speed up A/D conversions since a memory access from flash memory will be faster than from
EEPROM. Use anaSaveCalib to save the current set of calibration constants for the analog input and
output channels in the Smart Star flash memory. The calibration constants stored in flash memory can
then be accessed at any time with the anaLoadCalib function.
If the factory-set calibration are not used, customer-measured calibration constants should first be estab-
lished using the anaInCalib function.
None.
Reads a complete set of calibration constants for the analog input and output channels from the Smart
Star flash memory on the CPU Card. These should be set using the anaInCalib or anaInEERd func-
tion, then saved to flash memory using the anaSaveCalib function.
None.
