The instrument is applied using appropriate insulated operating poles, which quickly and simply affix to the base of the instrument with a ‘universal spline’ attachment. Hooking the Halo around the conductor, the peak reading of the rms current can be stored on a large clear LCD display and retained until reset. Typical applications include spot load surveys, phase balancing on primary and secondary circuits and monitoring of current flow through high voltage fuses to establish their integrity. The rugged design makes this instrument ideal for field use and is used by power utilities throughout the world. Padded carrying case and full instructions included.
