Q: Is the HONE measuring the humidity within the body of the guitar or the humidity of the room?

A: When mounted on top of the string of the guitar within a closed guitar case, the sensors are measuring and displaying the humidity from within the body of the guitar.  With a closed guitar case there is minimal air flow, therefore, the sensor is only reading the humidity from within the body of the guitar, not the entire case.

If you have the guitar wall mounted in open air, the sensor will be reading a mixture of humidity exiting the sound hole and humidity of the open-air environment that is also passing over the sensor.


Q: What does "LL" & "HH" mean on the LCD Display?

A: The HONE reads a humidity range of 20% - 99% and temperature range of 32 F - 122 F / 0 C - 50 C, if your humidity or temperature are below those ranges the reader will readout "LL", if they are above those ranges the reader will read out "HH".


Q: My screen won’t turn on, what can I do to fix?

A: First, replace the battery with a new AG13 battery.  If the screen still does not turn on, ensure the negative side of the battery is facing down into the unit and the positive side is facing you.  If the screen still does not come on, sometimes the contact gets bent and the battery is no longer making contact to power the screen, push battery down and see if the screen illuminates.  If so, fold up a small piece of paper/foam and place on positive side of battery.  Slide the battery door shut, this will allow the battery to make proper contact and illuminate the screen.
