1
Range overhead of ~5% on all ranges guarantees that full-scale values will not cause over range
2
Typical effective resolution (ER) in bits; computed from ratio of full-scale range to RMS resolution.

50/60 corresponds to rejection of 50 and 60 Hz ac power mains noise.
Accuracy (does not include sensor or measurement noise):
l 0 to 40 °C: ±(0.04% of measurement + offset)
l –40 to 70 °C: ±(0.06% of measurement + offset)
l –55 to 85 °C (XT): ±(0.08% of measurement + offset)
