OPERATION
ACCURACY
Accuracy is specified for a period of one year after calibration
and at 64.4ºF to 82.4ºF (18ºC to 28ºC), with relative humid-
ity < 75%. Except the ranges which are specified specially,
accuracy is specified from 8% to 100% of range.
Accuracy specifications take the form of:
± ([% of Reading]+[number of Least Significant Digits])
