ET40 is an Electronic AC/DC Voltage Tester. It features indicators for positive and negative DC polarity and tests DC voltages as low as 1.5V. It tests AC voltages 12-240VAC. Excellent for checking, verifying or troubleshooting common residential electrical wiring in electrical outlets, light fixtures, doorbells and more.
Identifies and distinguishes between AC or DC voltage
Tests AC voltages from 12V to 240V AC at four useful levels aligned with commonly used residential voltages
Tests DC voltages from 1.5V to greater than 17 to 24V at four useful levels aligned with commonly used DC voltages
Bright LEDs illuminate to indicate the type and level of voltage detected
Built to withstand a 9.9-Foot (3 m) drop
Indicates polarity when measuring DC voltages
Powers off automatically after approximately 2 minutes of non-use to conserve battery life
Built-in test lead holders on sides of tester
Low battery indicator with easily accessible battery compartment
Pocket clip secures tester to pocket for reliable everyday carrying
