Description

  The present invention relates to a measurement probe device used for measuring electrical characteristics in a device to be measured.

  In the conventional measuring probe apparatus, the tip of the probe is connected to the measurement point of the electric device to measure the potential and the like. However, for example, when connecting a probe to a measured point in the apparatus, the measured point may be located in a narrow place or a dark place, and a situation occurs in which connection of the probe is difficult. Also, when performing measurement, if the measurer is away from the oscilloscope, it is not possible to confirm the measurement contents on the spot.

  Therefore, there has been proposed an oscilloscope system which is provided with a remote display for displaying the same contents as the display contents of the display of the oscilloscope main body and can confirm the measurement contents even at a place away from the oscilloscope (for example, see Patent Document 1).

  In order to achieve the above object, the measurement probe device according to the present invention is provided with an illumination lens for illuminating the periphery of the point to be measured and a photographing lens for imaging the periphery of the point to be measured at the tip of the probe A remote display for displaying an imaging result by a lens, and a control device for controlling an illumination and an imaging function of the probe are provided.

  Further, the tip of the probe is provided with a metal hook for connecting the probe to a measurement point.

  In addition, the probe is characterized in that it has an angle adjusting mechanism which bends the tip of the probe to adjust the angle.

  Furthermore, it is characterized in that it comprises an expansion and contraction mechanism that adjusts the probe length by expansion and contraction of the tip of the probe.
