Actual performance is typically much better than the rated values. Please see the Rated Absolute Accuracy chart below.
Accuracy figures can be improved by recalibration. |
Rated Temperature Reading Resolution |
Less than 0.1°C for -40°C to +40°C.
Less than 0.2°C for +40°C to +80°C.
Less than 0.6°C for +80°C to +99°C.
Please see the Rated Native Resolution chart below.
LogTag Analyzer® currently displays to one decimal place of °C or °F. The native resolution is what is stored in the LogTag®. |
