Note The typical and maximum specification given in this data sheet are based on respectively 1 σ (68.27%) and
5 σ (99.9999%) statistical evaluations of calibration results. Cards exceeding the maximum specifications are
not released for sale. All specifications are defined at 23 °C
±
2 °C, unless specified differently.
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.
