The Extech VT30 digital voltage tester with a bargraph uses a backlit LCD display to test AC voltage from 0 to 480V and DC voltage from 0 to 690V. Polarity detection uses LEDs for both positive and negative DC detection.
The Extech VT30 digital voltage tester has two handed operation for low impedance testing, a built-in flashlight for testing in tight areas and the voltage function operates without a battery for continuous use.
