How to determine whether the oscillation of the humidifier?
Unable to determine whether it oscillates, can find a semiconductor radio station in no position, full volume (about 30cm or less) near the humidifier, humidifier and then open the power switch, if the received noise interference (noise affected by fog, the fog volume control potentiometer is large, strong oscillation noise; fog hour oscillation weak small noise) that humidifier oscillation. Conversely, the noise is not received, that is, the humidifier is not oscillating
When the vibration of the humidifier is very weak, the fog produced by the energy exchange plate is not obvious
As long as the humidifier can spray, that is, the oscillator has been working
