NOTE! Accuracy specifications consist of two elements:
(% reading) – This is the accuracy of the measurement circuit.
(+ digits) – This is the accuracy of the analog to digital converter.
NOTE! Accuracy is stated at 65°F to 83°F (18°C to 28°C) and less than 75% RH.
Safety: For indoor use and in accordance with Overvoltage Category II, Pollution Degree 2. Category II includes local level,
appliance, portable equipment, etc., with transient overvoltages less than Overvoltage Category III.
