Blue Ring Tester Schematic Diagram Direct

A Blue Ring Tester, also known as a voltage tester or circuit tester, is a handheld device that indicates the presence of voltage in a circuit without making physical contact with the conductors. It is a crucial tool for ensuring electrical safety and is commonly used for testing voltage in outlets, switches, and other electrical devices.

The Blue Ring Tester works on the principle of capacitive coupling. When the tester is brought near a live circuit, the high-impedance resistor (R1) allows a small amount of current to flow through the capacitor (C1) and into the circuit. If voltage is present, the neon lamp (NE1) will glow, indicating that the circuit is live. A Blue Ring Tester, also known as a
