Dual-Range AC Voltage Detection

This non-contact tester covers 12-1000V AC in high-sensitivity mode and 70-1000V AC in low-sensitivity mode. An LCD screen shows a bar graph and percentage value that rise with signal intensity. Red and green backlighting plus audible beeps indicate live or null wires. It is rated CAT III 1000V and CAT IV 600V for professional safety.

Electricians and Homeowners Checking Live Circuits

Suitable for anyone tracing breakpoints, testing outlets or verifying doorbell and thermostat wiring without contact. The adjustable sensitivity helps separate low-voltage control circuits from mains. Not intended for users who need DC measurement, continuity testing or current-clamp functions.

Sustained Use on Site

Automatic power-off after five minutes of inactivity conserves the two AAA cells. A low-battery symbol appears when voltage drops below 2.5V and operation stops below 2.3V. The double-insulated housing and high-voltage alert above 90V remain active throughout extended sessions.

Questions about this item

What batteries must I already have to power the KAIWEETS KTL01 voltage tester?

The tester runs on two 1.5 V AAA batteries, which are not included with the unit.

Will the tester still detect voltage on older 12 V AC circuits such as doorbell or thermostat wiring?

Yes, the high-sensitivity mode covers 12 V to 1000 V AC, so low-voltage circuits are detected; press the S button to select this range.

How can I confirm the KTL01 is operating correctly after I install the batteries?

Bring the tip near a known live AC source; the tip LED should flash red, the buzzer should sound, and the LCD should show a percentage value and bar-graph indication.
