How to prevent oscilloscope current probe damage?

The oscilloscope probe is crucial to the accuracy and correctness of the measurement results. It is an electronic component that connects the circuit under test to the input terminal of the oscilloscope and is an indispensable accessory for the oscilloscope. The oscilloscope current probe is a magnetic ring designed based on the Faraday principle to measure the interference current signal in the wire. It is essentially a transformer with 1 turn. The current probe can be used to measure the current flowing through the wire.

Although the oscilloscope current probe is just a small accessory, it is indeed indispensable for electronic engineers. Moreover, the probe is a consumable item and is easily damaged. Antai Testing has found that the parts of the probe that are easily damaged are roughly as follows through the fault analysis of damaged oscilloscope current probes:

1. 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. After the current amplifier is powered on, the circuit board is damaged by plugging and unplugging the current probe.

Remember not to plug or unplug the current probe while it is powered on.

2. The magnetic ring is a fragile material. It is easy to break if it is dropped or used with excessive force. A damaged magnetic ring will cause inaccurate testing or no current can be measured.

Avoid dropping or applying excessive force when using

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

Avoid overcurrent when using

4. If the current clamp is not aligned or has cracks, the test will be inaccurate or the current cannot be measured. Note that you should be careful when pushing the clamp.

The current clamp should be aligned when in use. Pay attention and be careful when pushing the clamp.

5. The cable will be easily damaged if it is pulled or twisted too hard.

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

The operation method provided above is relatively simple and can be done with a little attention. However, operators are often prone to neglect it in their tense and busy work. We hope that users will pay attention to reduce unnecessary damage to the oscilloscope current probe.

The probe is a precision accessory instrument and an indispensable accessory of the oscilloscope. Without the probe, the oscilloscope cannot work. Antai Testing specializes in repairing various oscilloscope probe models:
