Abstract
A low cost hook-on ammeter for consumer use includes a split core to be clipped around a conductor. Secondary turns on the core actuate a liquid crystal digital display to indicate alternating current amplitude in the conductor. The liquid crystal display segments may be connected to individual taps on the secondary winding, or to taps on a resistive divider network connected across the entire secondary winding. As current in the conductor increases, secondary voltage increases, turning on an increasing number of segments of the liquid crystal display accordingly.
