Active probe

摘要

The Probe I is a diagnostic tool for use by electricians, technicians, as well as people with only elementary knowledge of electricity. Its value lies in its ability to screen test many simple as well as complicated components, by using visual as well as audio signlas, to compare the sound of a known good component to the one being tested. Many circuits can be repaired without any idea of what the circuits actually do, and many times without prints for the circuit.
