Wilmar W2990 LED Digital Circuit Tester
Ideally used to detect power, voltage, ground, and circuit integrity. Large LCD display provides a 'no guess' voltage value of the circuit tested. Surge protected circuitry displays DC Voltage from 3 to 48v (� 0.3V accuracy). Backlit LED glows red for power and green for ground. Computer safe <10mA circuit draw for confident testing. (Do not use on airbags.) Recoil lead wire stretches safely from 3 to 12 feet. Durable storage case for tool protection The professional technicians can detect voltage, power, ground and circuit integrity with increased accuracy and ease. LED indicates red for "power" or green for "ground" from 3v to 48v.
