Operation
Open the clip and clamp onto a headstock or other contact
surface. Pressure pads in the clip will switch on the power.
Play a note and the contact pickup will detect the pitch - the
display states the nearest note and a virtual needle shows
the tuning status. If the note is not correct, tune the
instrument closer to pitch until the correct note is shown.
If the needle is to the left, the note is flat
and the display will be lit in a red colour.
If the needle is in the centre, the note is in tune
and the display will be lit in a green colour.
If the needle is to the right, the note is sharp
and the display will be lit in an orange colour.
Removing the clip from the instrument will switch off the
power. 5 minutes without any note detected will also switch
off the power.
