The interface is somewhat intentionally obtuse -making the use of this instrument rely on trial and error rather than explicit information made available to the user. The top left switch allow the user to swap between a mode for sensing wifi signals or a mode for sensing EMF signals. The top right swaps between using the long directional antenna or round non directional antenna.
The left knob controls the signal low threshold cut-off (any signal below this value is not registered on the motor) and the right knob controls the high threshold cut off which also affects the sensitivity as the signal is remapped between 0 and the high threshold value. Due to the noise of the various emf devices including the particle itself it's necessary to adjust these for each environment.
The lower most switch is connected to the enable pin on the particle argon - effectively an on/off switch for the device.
The process of using the device requires a lot of fiddling with the knobs in order to dial in a setting where the device is registering desired emf signals but not activating constantly. This makes the device's function somewhat mysterious and enigmatic - to be used only by an experienced practitioner. However, this process is not merely poetic as it is the same process necessary to isolate electronic signals for analysis which can prompt consideration to how we differentiate "signal" from "noise".
