How to prevent damage to oscilloscope current probes

 　　The oscilloscope current probe is a magnetic ring designed based on Faraday's principle to measure interference current signals in wires. It is essentially a transformer with 1 turn. Use a current probe to measure the amount of current flowing through a wire.

　　Through fault analysis of damaged oscilloscope current probes, it was found that the easily damaged probe parts are roughly as follows:

　　1. The circuit board connected to the current amplifier;

　　2. The magnetic ring of the current probe is broken;

　　3. Magnetic ring coil of current probe;

　　4. The appearance of the sliding clip of the current probe is damaged;

　　5. The cable is broken.

　　Causes of damage to oscilloscope current probes, methods to prevent damage and instructions for use. The causes of damage to the above five parts can be summarized as follows:

　　1. Damage to the circuit board caused by plugging and unplugging the current probe after the current amplifier is powered on.

　　Remember not to plug or pull out the current probe while the power is on

　　2. The magnetic ring is a fragile material and can easily be damaged if it is dropped or used with excessive force. A damaged/damaged magnetic ring will cause inaccurate testing or the current can no longer be measured.

　　Avoid dropping it or using excessive force when using it

　　3. The magnetic ring coil is relatively thin, and overcurrent will cause the coil to burn out.

　　Avoid load overcurrent when using

　　4. If the current clips are not aligned or have cracks, the test will be inaccurate or the current cannot be measured. Note, be careful when pushing the clip.

　　The current clamps should be aligned when using them. Pay attention and be careful while pushing the clamp process

　　5. Cables may be easily damaged if they are pulled or twisted too hard.

　　Do not pull or twist the cable too hard when using it.

　　The operation methods provided above should be said to be relatively simple and can be accomplished with a little attention. However, operators are often prone to neglect during tense and busy work. This is just another reminder to the user.
