Dual-Range Voltage Detection

The KAIWEETS tester covers 12V to 1000V AC in high-sensitivity mode and 70V to 1000V AC in low-sensitivity mode, letting electricians and homeowners check everything from doorbell circuits to mains supply. A simple press of the S button switches ranges, while the LCD shows both a bar graph and a percentage value for quick signal-strength assessment.

Handheld Non-Contact Operation

No test leads are required; the inductive tip senses AC voltage through insulation, so the tool fits in a pocket and works inside crowded panels without exposing conductors. Automatic live/null identification lights the screen red for live wires and green for neutral, and a built-in breakpoint finder helps trace opens in irrigation or thermostat wiring. Two AAA 1.5V cells power the unit, which shuts off after five idle minutes.

Safety-Rated Alerts

The tester meets IEC CAT III 1000V and CAT IV 600V standards with double insulation. Above 90V the display turns red, a safety symbol flashes, and the beeper frequency rises with voltage level or proximity. A low-battery symbol appears when cell voltage drops below 2.5V, and the tool powers down completely under 2.3V to prevent false readings.
