How to avoid damage of oscilloscope current probe

Through the fault analysis of the damaged current probe , It is found that the probe parts that are easy to be damaged are ：

1. A circuit board connected to a current amplifier ;

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

3. Magnetic loop coil of current probe ;

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

5. Cable break .

The reason why the current probe is damaged , Methods to prevent damage and instructions for use. The reasons for the damage of the above five parts can be summarized as follows ：

1. After the current amplifier is powered on , Circuit board damage caused by plugging in and out current probe .

Ways to prevent damage —— Remember not to plug and unplug the current probe with power

2. Magnetic rings are fragile materials , It is easy to break if it falls to the ground or is used too hard . There is damage / Damaged magnetic ring will cause inaccurate test or no more current measurement .

How to prevent damage and use ：—— Avoid falling or exerting too much force when using

3. The magnetic ring coil is thin , Overcurrent will cause the coil to burn .

Ways to prevent damage —— Avoid overload when using

4. The current clip is not aligned , Cracks will make the test inaccurate or unable to measure the current . Be careful , Be careful when pushing the clip .

Ways to prevent damage —— When using, the current clamp shall be aligned . Be careful , And be careful when pushing the clip

5. The cable is pulled too hard 、 Twisting, etc. will be easy to damage

Ways to prevent damage —— Do not pull the cable too hard 、 Torsion, etc .

The operation method provided above , It should be said that it is relatively simple , Pay attention, , It can be done , However, operators are often prone to neglect in tense and busy work . Here is just another reminder to users .
