Once the residual voltage drops to approximately 6V, the LED turns off, signalling that the discharge cycle is complete. Note that a small residual charge of ~6V may remain.\u003c\/p\u003e\n\u003ch4\u003eQ: Is it safe to use the discharge pen on high-voltage capacitors repeatedly?\u003c\/h4\u003e\n\u003cp\u003eA: The pen is rated for up to 1000V and discharges spark-free. For repeated use on high-capacity capacitors, allow the internal MOSFET component to cool between cycles to maintain safe operation and extend tool longevity.\u003c\/p\u003e\n\u003ch4\u003eQ: Does the probe spacing adjust to fit different capacitor footprints?\u003c\/h4\u003e\n\u003cp\u003eA: Yes.
