Ground loopsWhen making high-frequency voltage measurements above 40MHz, it is highly recommended to use this included alligator clip for a direct ground connection instead. This connection significantly reduces parasitic inductance and capacitive effects on the ground circuit, thus improving the frequency response characteristics of the entire measurement system. Better high-frequency response means you can capture more realistic and detailed signal waveforms, greatly improving measurement accuracy and data reliability. |
High insulationThe high-voltage probe is made of selected cutting-edge insulating materials combined with advanced manufacturing processes, and its core advantage is excellent insulation performance. The design effectively isolates high-voltage interference, eliminates the risk of potential leakage, and ensures that the measurement signal remains pure, stable, accurate and reliable even in harsh ultra-high voltage environments. The excellent insulation performance eliminates false detection and potential safety hazards, and greatly improves the safety of equipment and operator protection. |
