Accuracy guarantee for
temperature and humidity
23°C ± 5°C (73°F ± 9°F), 80%RH or less
(non-condensating)
Temperature characteristic Adds “Measurement accuracy × 0.1/°C”
(excluding 23°C ± 5°C (73°F ± 9°F)).
• rdg. (reading or displayed value): The value currently being measured and
displayed on the measuring instrument.
• dgt. (resolution): The smallest displayable unit, i.e., the input value that
causes the digital display to show a “1” as the least-signifi cant digit.
