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 the Hioki Memory HiCorder by visualizing signals from electric equipment simply by applying the probe to the wire’s insulation

• Capture signals from electric equipment and communication lines

• 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
