Mount the transmitter vertically using expansion screws, keep the sensor below the unit, place it at human‑height level, and avoid direct sunlight, windows, or nearby high‑power equipment.
It is recommended to calibrate the transmitter at least once a year to maintain measurement accuracy.
Store the transmitter at 10 °C–40 °C with relative humidity of 20 %–80 %.
