CURRENT PROBE

CT6700

High S/N characteristic ideal for ultra low 1 mA order current waveforms Clearly Observe Even 1 mA Waveforms

Hioki flat bandwidth current probes are best-in-class current sensors for use with Memory HiCorders and high performance oscilloscopes. The CT6700 is a high-sensitivity current probe that offers a wide DC to 50 MHz bandwidth and 5A of continuous input, and applications include capturing transient current signals from switching power supplies, inverters, and motor controllers. The probe is designed with a high permeability magnetic shield to reduce the effects of electric fields, making it ideal for measuring low currents or nearby high-current lines. Key Features • Wide band: DC to 50 MHz (-3 dB) • High S/N characteristic ideal for ultra low 1 mA order current waveforms • Connect directly to an oscilloscope’s BNC input terminal *1 Also available: CT6701 with wider bandwidth from DC to 120 MHz (-3 dB) *1 Connecting the device’s metal BNC terminal to a Memory HiCorder’s plastic BNC terminal may damage the plastic terminal or cause it to become misshapen.

CT6700 From 1mA, 50MHz bandwidth

Note: Use optional Power Supply 3269 or 3272 to drive the current probe when power from the Memory HiCorder or oscilloscope is not available. Exercise care concerning offset drift when performing continuous measurement over extended periods of time.

High Signal-to-Noise Ratio

Hioki-manufacturered Hall elements deliver probes characterized by low noise across a wide bandwidth, letting you measure current at a high signal-to-noise ratio so that even minuscule currents don’t get lost in the noise.


One-touch Disconnection from the BNC Terminal

Easily connect the probe with your oscilloscope or recorder without twisting or turning the connector. Simply insert the connector until it automatically locks into place. Use the unlock lever and pull to detach.


Automatic Zero-Adjustment and Demagnetization with a Single Button

Zero-adjustment and demagnetization must be conducted before each measurement to null out any residual signals and remove any magnetic fields from the previous test in order to provide an accurate and repeatable output. The CT6700 is designed with an automatic zero-adjustment and demagnetization feature that can be activated with a single button to cancel any offset margin of error after measuring a large current.
