The Model 275HVD is designed to detect the presence of high voltage without physical contact.
An eight position rotary switch selects the detection range. As the sensor is moved closer to the voltage carrying conductor, its sensor head picks up the radiated electric field. Once the threshold is reached, the buzzer sounds and a bright red warning light warns the operator of live conductors.
The Model 275HVD is powered by three standard Alkaline C cell batteries and can be used both in- and out-of-doors. A universal spline on the back-end facilitates attachment to any standard hot stick. A self-test position ensures that all circuitry and annunciators are working properly before use.
