Accuracy ±1% or higher, initial impulse response for all models, with high impedance loads, such as 1 megOhm in parallel with 20 pF. The 50 ohm terminal will reduce the output by half. All models listed below come with BNC connectors, unless otherwise noted, and work with 50 ohm coaxial cable. The current monitor housing is conductive, not marginal. Adequate edges must be provided on the conductor being monitored. To avoid electric shock, do not install or remove the current monitor on the live conductor.
