701917 Current Probe 50 MHz / 5 ARMS

What is the 701917 Current Probe?

701917 is a low noise compact current probe for measuring low-level currents from 1 mA to 5 A. Best suited for design and verification applications requiring high-sensitivity at low currents.

Frequency bandwidth: DC to 50 MHz

Maximum continuous input range: 5 Arms

Functions with Digital Oscilloscopes, ScopeCorders, and other waveform measuring instruments

How does a Current Probe Work?

Conductors' current flows cause electromagnetic flux fields. Oscilloscope current probes detect the fields' strength and convert it to voltage for an oscilloscope to measure for waveform analysis.

How to use a 701917 Current Probe

Before measuring, check that there are no problems with the instrument or the measurement target and that measurement preparations have been taken.

1. Pull the sensor opening lever to open the sensor head.

2. Align the direction of the arrow of the current direction mark indicated at the sensor tip to the direction of the measured current, and clamp so that the conductor is at the center of the sensor aperture. Low potential side (ground potential side) High potential side

3. Hold down the sensor opening lever until the JAW UNLOCKED indication disappears to lock the sensor head. The JAW UNLOCKED LED turns off.

4. You can observe the current waveform on the waveform measuring instrument. The output voltage rate of the 701917 and 701918 is 1 V/A. Convert the voltage sensitivity of the waveform measuring instrument to current sensitivity. For example, if the voltage sensitivity of the waveform measuring instrument is 10 mV/DIV, the current sensitivity is 10 mA/DIV.
