Operation

3.

The normal operating temperature range is between 60º and 90º F (15º and
32º C). If used outside this range, an additional error will be introduced. This
error can be approximated as -0.1% per Fahrenheit degree. The negative
temperature coefficient means that the instrument reads high at lower
temperatures and low at higher temperatures.
