Features Insulating Cap: The oscilloscope accessory is equipped with an insulating cap to cover the exposed metal part of the probe tip to prevent leakage and ensure safe use. The BNC test lead kit has high accuracy and is suitable for all standard BNC head oscilloscopes. Grounding spring: the P4250 oscilloscope probe is equipped with an earth spring, which is attached to the front of the probe head for grounding, which can improve the high frequency response. The probe needle can be used to reliably earth the probe, which is convenient for safe operation and reading the correct signal DIFFERENT COLOR MARKER RINGS:The BNC test lead kit is equipped with different color marker rings to identify different channels. Sample is an excellent choice for oscilloscope probe. The probe is small and has multiple functions in one that is easy to use.
