Note The specifications listed are valid for cards that have been calibrated and are used in the same mainframe and
slots as they were at the time of calibration. When the card is removed from its original location and placed in
another slot and/or mainframe, the Offset error, Gain error and MSE specifications are expected to increase
(up to double the original specification) due to thermal differences within the configurations. All specifications
are defined at 23 °C
±
2 °C, unless specified differently.
