72 Calibration
recommended for users to adjust the on-board calibration refer-
ence except when an ultra-precision cali-brator is available.
Note:
1. Before auto-calibration procedure starts, it is recom-
mended to warn up the card for at least 15 minutes.
2. Please remove the cable before an auto-calibration pro-
cedure is initiated because the DA outputs would be
changed in the process of calibration.
5.3 Saving Calibration Constants
After an auto-calibration is completed, users can save the new cal-
ibration constants into one of the three user-modifiable banks in
the EEPROM. The date and the temperature when you ran the
auto-calibration will be saved accompanied with the calibration
constants. This means users can store three sets of calibration
constants according to three different environ-ments and re-load
the calibration constants later.
