Capture Voltage Signals from Outside the Wire Cover

The SP3000 is a non-contact AC voltage waveform probe ideal for maintenance applications involving device control signals and sensor signals. Simply apply the probe to a cable outside its insulation cover to capture the signal without exposing the technician to electrocution.
Key Features
      • Observe waveforms with an oscilloscope or a Hioki Memory HiCorder by visualizing signals from electric equipment simply by applying the probe to the wire’s insulation
      • Capture LIN and other communications signals
      • Measure signals from electric equipment on vehicles
      • Ideal for applications where:
        – Miniaturization of devices and use of waterproof connectors make it impossible to establish contact with metal terminals.
        – Connectors can’t be removed due to reduced ability to reproduce phenomena.
        – There is need to avoid tearing the wire insulation so as to prevent risk of damage to the sensor due to static electricity.

Model No. (Order Code)

SP3000-01 SP3000, SP9001 bundled model

Connect to a Memory HiCorder’s analog input terminal or oscilloscope. Both the SP3000 amplifier box and SP9001 probe head are necessary to measure. Select Model SP3000-01 for the entire system.

A comment from the Good Design Award 2017

“First, this award recognizes Hioki’s proprietary no-metal-contact measurement technology, which allows measurement of voltage waveforms from outside a wire’s insulation, without any need to make contact with a metal terminal. Further, it recognizes the product’s technology and design, for example in terms of the implementation of that technology in an instrument that can be applied to wires single-handedly in confined locations and designers’ success in creating a small, hands-free probe that need not be supported by the end-user.”
