Potentiometer Continuity Testing

Required Materials• Multimeter• Potentiometer

Multimeter

Potentiometer

Continuity Testing• Shows the amount of

electricity permitted to pass through Potentiometer by measuring resistance Ω (ohms)

Page 4: Electric Guitar Controls

Potentiometer Testing cont.• Set Multimeter to 2000K

Ohms • Then connect red probe to left

connection and black probe to middle.

Potentiometer Testing Cont.

Turn fully counter-clockwise for max ohmsTurn fully clockwise for zero ohms

500K ohms 0 K ohms

Potentiometer Testing Cont.

Turn fully counter-clockwise for zero ohmsTurn fully clockwise for max ohms

500K ohms0 K ohms

Reversed

Page 8: Electric Guitar Controls

Potentiometer Testing cont.

Turning in either direction causes no significant change

Shows max capacity of ohms

Volume Control Potentiometer is

grounded on one side

Signal from pickup

Signal out to amplifier

Page 10: Electric Guitar Controls

Tone Control Potentiometer plus

capacitor makes tone control

“Low Pass Filter” Blocks high

frequencies Only allows low

frequencies to pass Signal from pickup

Capacitor is grounded to back of case

Page 11: Electric Guitar Controls

Volume and Tone together

The cases of the potentiometers are tied together and ground

Selector switch for pickups

Signal to
