Hioki 3273-50 - 50MHz 30A AC/DC Current Probe

Names of Parts

Parts of the Sensor:

1. Opening lever Operating lever for opening the sensor head. Always use this lever to open the sensor head.
2. Sensor head This clamps the conductor being measured, and carries out the actual current measurement. It is a precision assembly including a molded component, a ferrite core, and a Hall effect element. It may be damaged if subjected to sudden changes in ambient temperature, or mechanical strain or shock, and therefore great care should be exercised in handling it.
3. Demagnetizing switch (DEMAG) This demagnetizes the core if it has been magnetized by switching the power on and off, or by an excessive input. Always carry out demagnetizing before measurement. The demagnetizing process takes about one second. During demagnetizing, a demagnetizing waveform is output.
4. Zero adjustment dial (ZERO ADJ) Use the zero adjustment dial to correct for the effect of a voltage offset or temperature drift on the device. When beginning measurement, after demagnetizing always carry out zero adjustment.
5. Coarse adjustment trimmer Use this only when adjustment is not possible within the range of the zero adjustment dial.Use a nonconductive screwdriver (e.g. ceramic driver) for adjustment.
6. Output connector The current waveform of the measured conductor is output at a constant rate (0.1 V/A). Connect to the BNC input connector of the waveform measuring instrument.
7. Power plug Connect this to the 3269 or 3272 POWER SUPPLY receptacle to supply power to the sensor terminator.
