• Full-scale Accuracy - Variation in the measured output voltage from the theoretical full-scale output voltage at

1x attenuation. The following formula is used to calculate full-scale accuracy:

• Relative Accuracy - Variation in the measured output voltage from the theoretical attenuated output voltage at

each of the attenuation ranges. The following formula is used to calculate relative accuracy:

• Full Scale Drift - The variation of the measured full-scale voltage across the specified temperature range.

• Common Mode Drift - The variation in the measured common mode voltage across the specified temperature

range.

full scale accuracy =

measured full scale voltage - theoretical full scale voltage
