• 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.
