Abstract
An earring force tester for clip-on type earrings detects the spring force of an earring and provides a visual output signal including whether the spring force is above (too tight), below (too loose) or within an acceptable range of force. The output signals are different colored LEDs. The lower and upper boundaries of the range can be adjusted such as to calibrate the device.
