Extech ET50 vibrating solenoid voltage tester will display the voltage level and vibrate slightly. When
DC voltage is detected, the voltage and polarity with be displayed but the tester will not vibrate.
The Extech ET50 vibrating solenoid voltage tester features retractable test prods that can be locked in
the retracted position for continuous use. The Extech ET50 vibrating solenoid voltage tester is sold in
