I am attempting to replace the buzzer in a craftsman digital multimeter. The unit runs off a 9-volt battery. The buzzer in the unit measures 12 mm wide and 8mm high. There is no identification on the current buzzer other than a +. Can anyone make an educated guess as to what buzzer would be an appropriate replacement? A Digi-Key part number would be great.
This might be a long shot, but take a look at these parts. They are 5VDC parts, since I would assume the the 9V from the battery is stepped down internally. They are all 12mm in diameter with varying heights.
I purchased 4, 12mm magnetic buzzers all with different volt ranges. I installed a 3-7VDC, Digi-Key Part # 433-1081-ND, buzzer and the meter works great. The new buzzer is easier to hear and the sound is smoother. Thank you for your input
