1kV – 40kV Multi-Range Voltage Detector w/Lighted Dial: Powered by the unit’s internal battery (included), a long-life bulb gives a glow to the meter face so the scale is easy to read in most conditions. To conserve the battery, a special switch locks the light off when not in use. Its spring-loaded toggle must be pulled up to move it over the stop between its on and off positions.
