Set Reference Temperature (e.g., 25°C):
Initialize each transducer by loading its respective
register with default coefficients (e.g., based on
mean values of offset, FSO, and bridge resistance)
to prevent overload of the MAX1455. The internal
calibration registers are addressed in ICRA[3:0]
and decoded as shown in Table 15.
Set the initial bridge voltage (with the FSODAC) to
half of the supply voltage. Measure the bridge volt-
age using the BDR or OUT pins, or calculate based
on measurements.
Calibrate the output offset and FSO of the transduc-
er using the ODAC and FSODAC, respectively.
Store calibration data in the test computer or
MAX1455 EEPROM user memory.
Set Next Test Temperature:
Calibrate offset and FSO using the ODAC and
FSODAC, respectively.
Store calibration data in the test computer or
MAX1455 EEPROM user memory.
Calculate the correction coefficients.
