FAQs
Q1: How does this tester pen distinguish between a Live (Fire) and a Zero (Null) wire?
A: It uses an intuitive dual-alert system. When detecting a Live wire, the LCD screen turns red and the buzzer sounds rapidly. For a Zero wire, the screen turns green and the buzzer sounds slowly.
Q2: Can the XT89 help me find a break inside an insulated wire?
A: Absolutely! Using its non-contact voltage (NCV) detection, simply slide the pen along the insulated wire. The point where the beeping stops or drops significantly is exactly where the internal breakpoint is located.
Q3: What is the AC voltage measurement range for this device?
A: The XT89 is designed to accurately detect and display AC voltages ranging from 12V to 300V. The exact voltage reading is displayed clearly on the digital screen.
Q: Can I use this tester in dark electrical boxes or at night?
A: Yes, it features a built-in bright LED flashlight near the probe. It serves as an excellent emergency light, ensuring you can see terminal boards and sockets clearly in dark environments.
