my multimeter has been bugging me with this buzzing sound that turns on and off while I'm using it. I think it has something to do with its autoranging feature, but I couldn't find the manual for this one and have a mind to get rid of the buzzing if it won't stop.
Page 21 of the user manual states:
WRONG CONNECTION INDICATION
The [buzzer] icon will appear in the upper right corner of the display and the buzzer will sound whenever the positive test lead is inserted into the 20A or uA/mA input jack and a non-current function is selected. If this occurs, turn the meter off and reinsert the test lead into the proper input jack for the function selected.
You can disconnect it or just avoid having the leads in the wrong socket.
Pager or vibration motor. It spins with an offset weight to vibrate and buzz. It's for buzzing. Cut the wire and it won't buzz any more. Or replace it with an LED or something if you want.
