FAQ – Frequently Asked Questions
1. What is the difference between low and high detection ranges?
Low range (12–1000V) identifies low-voltage wiring like thermostats or data cables, while high range (70–1000V) is ideal for standard residential and commercial AC circuits.
2. Can this tester be used for DC voltage?
No. The NCVT2P is designed specifically for AC voltage detection only.
3. Is it safe for use on live circuits?
Yes—its non-contact design allows safe, hands-free detection without touching energized conductors.
4. Does it work outdoors or in bright light?
Yes. The red/green LED indicators are bright enough for outdoor use, and the audible tone helps confirm detection.
5. Does it require calibration?
No user calibration needed; factory-calibrated for accuracy.
6. Will it detect voltage through insulation?
Yes. It detects AC voltage through typical insulation, cable sheathing, and outlets.
7. What safety category does it meet?
It meets CAT IV 1000V, providing high protection for industrial and utility environments.
