When using a DC current probe, you need to pay attention to the following points:

　　The DC current probe is an instrument used to measure the current of DC circuits. The product has stable performance, is easy to use, and has accurate measurement. It usually consists of a metal pin and a sensor that measures the current and can accurately read the current value during the measurement process. The working principle is based on Ohm's law, which states that the ratio of current to voltage equals resistance. The sensor in the probe measures the resistance and converts it into a current value. This process requires the use of a built-in amplifier to amplify the current signal and output it to the measurement device.

　　DC current probes are generally divided into two categories: clip-on probes and plug-in probes. Clip-on probes can be clipped onto wires in a circuit and can be measured without cutting off the circuit. Plug-in probes require the probe to be inserted into an interface or socket in the circuit to make measurements.

　　When using a DC current probe, you need to pay attention to the following points:

　　1. Select the appropriate probe model. Different DC circuits require different probe models, so when purchasing a probe, you should choose the appropriate model based on actual needs.

　　2. Make sure the probe is safe. When using the clip-on probe, be careful not to get caught on exposed wires to avoid electric shock. Plug-in probes also need to be careful. The interface or socket they are inserted into should be dry, undamaged, and meet safety requirements.

　　3. Pay attention to the working status of the circuit. When performing circuit measurements, be sure to ensure that the circuit is in normal working condition, otherwise it may cause damage to the circuit.

　　4. Be familiar with the reading range of the probe. Different models of probes may have different reading ranges. You need to be familiar with the reading range of the probe before use to avoid errors or damage caused by exceeding the range.
