167. Suppose that a standard remote reading bourdon tube thermometer has a scale of 40 to 240°F. If the accuracy of the thermometer is plus or minus 1% of the span, what would the range of measured temperature be if the thermometer indicates 180°F?
The thermometer's span is 200F, and an accuracy of +-1% of the span allows for an error of +-2F. Therefore, an indicated temperature of 180F corresponds to a true temperature range of 178 to 182F.
