Accuracy ±1% or better, initial pulse response for all models, with a high impedance load such as 1 megOhm in parallel with 20 pF. A 50 Ohm termination will reduce the output to half. All models listed below come with a BNC connector except as noted and are to be used with a 50 Ohm coaxial cable. The current monitor case is conductive and not insulated. Adequate insulation must be provided on the conductor being monitored. To avoid electrical shock, do not mount or remove the current monitor from a live conductor.
