試験装置。 In a remote sensor testing device that sets upper and lower test modes based on the polarity of the voltage applied to the sensor test section, an increase in the operating current of the sensor is controlled by a photocoupler or relay connected to the sensor operation confirmation circuit of the sensor itself. The test power supply section, which is separate from the sensor, is supplied as a signal to the sensor test section installed inside the sensor through an insulated coupler such as operation of the sensor can be confirmed by increasing the current of the sensor and lighting up an indicator such as a light emitting diode connected in series with the power supply of the test power supply unit and provided within the test power supply unit. remote sensor testing equipment.
