Questions about this product
- What voltage range can this pen detect, and does it work on DC batteries?
- This tester detects AC voltage from 90V up to 1000V at 50/60 Hz frequencies. It does not work on DC power like car batteries or standard household AA batteries. You can only use it to test alternating current systems.
- Is this tester safe to use on live electrical panels?
- Yes, this pen has a CAT III 1000V safety rating for testing household circuits. The non-contact design uses capacitive sensing to detect live voltage without touching bare wires. This keeps you safe from accidental electrical shocks while troubleshooting.
- How do I use this tester to check if an outlet has power?
- Just turn the pen on and place the tip near the outlet's slots. If the outlet is live, the red LED indicator lights up and the alarm sounds. You can also use it to check electrical cords, switches, and appliances.
