How to use

Use the two‑point adjustment to calibrate the instrument if necessary, following the manufacturer’s calibration points to align readings with a reference thermometer.

Usage recommendations

Position the thermometer at typical head height indoors and in a shaded, ventilated location outdoors for the most accurate ambient readings. Avoid mounting near radiators, ovens, entry doors or windows to prevent distorted measurements. Periodically check the calibration and clean the housing with a soft cloth; do not use aggressive solvents.
