The Halo I is capable of taking spot-load studies at transformers or at any mid-span location, as well as phase balance studies on primary or secondary lines. HALO I is a true RMS reading instrument. Its load-latching circuitry continually latches and locks on to peak system currents. It will display and hold the reading until the display is reset.
