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])
