Hioki's clamp type AC/DC current sensors can be connected directly to Hioki Power Analyzers and Memory HiCorders. Also, it can be connected to Power Meters, Oscilloscopes, DMMs, etc. by using an optional sensor unit. The CT6840A series can measure current in operating vehicles since there’s no need to cut cables. Combined with a power analyzer, these instruments can accurately integrate current and power during charging and discharging of system batteries in order to make WLTP-compliant fuel efficiency measurements. While clamp-style current sensors are generally praised for their convenience, they usually pose disadvantages in terms of measurement precision. However, the CT6840A series delivers unparalleled measurement precision in a clamp-style design, allowing accurate measurement of DC power in battery-powered EVs and solar power systems. Use with an instrument with a high input impedance of 1 MΩ or higher.
