Hioki flat bandwidth current probes are best-in-class current sensors for use with Memory HiCorders and high performance oscilloscopes. The CT6710 is a 3-range, high-sensitivity current probe that offers a wide DC to 50 MHz bandwidth and 200 μA to 30 A input, letting your capture signals across an expansive current range, from steady state to transient currents, when developing switching power supplies, inverters, and motor controllers. Key Features • 3 ranges in a single probe - 30 A, 5 A, 0.5 A. Observe a wide current range from micro currents to 30 A. • Wide band: DC to 50 MHz (-3 dB) • High S/N ratio and 10 times output rate: Observe waveforms at 100 μA/div at oscilloscope maximum voltage sensitivity setting of 1 mV/div • Directly connect to an oscilloscope’s BNC input terminal *1 • Also available: CT6711 Current Probe with DC to 120 MHz bandwidth *1: Connecting the probe's metal BNC terminal to a Memory HiCorder’s plastic BNC terminal may distort or damage the plastic terminal. To avoid damage, please connect and disconnect the probe cable straight to the BNC terminal of the waveform monitoring equipment.

Note: If power cannot be supplied from the Memory HiCorder, the optional Power Supply 3269 is required. Please pay attention to offset drift during continuous, long-term measurement.
Insulated conductor
3 Full Ranges of 30 A, 5 A, And 0.5 A Deliver an Expansive Current Measurement Spectrum
Monitor current under a broad range of operating conditions from 0.5 to 30A. Simply press the RANGE key on the termination box to toggle between ranges, and analyze everything from sudden inrush to slow moving consumption current, down to micro currents of low energy devices, all with a single device.
Built-in Function to Protect Against Excessive Input
When input exceeds the rated value, a warning indicator flashes to signal a warning. In addition, if you select the incorrect range and then input a current signal that is above the rated current for that range, this function protects the instrument from damage due to overheating. Caution: Input currents that exceed the frequency derating for the 30 A range may cause measurement circuit damage before the protection function kicks in.
High Signal-to-Noise (S/N) Ratio
Observe waveforms as they are without needing to rely on your oscilloscope’s filter settings and averaging function. The 10V/A output rate is 10 times the traditional 1V/A rate of legacy products, allowing you to improve the oscilloscope’s voltage sensitivity by a factor of 10, thereby enhancing the S/N ratio of the scope itself to deliver much clearer waveforms.
