- Warning buzzer triggered at 100Ω or less.
- LED lights up when a large earth voltage is detected.
- Live circuit warning when 30V or higher voltage is detected. (KEW 4300 detects voltage even when measuring resistances.)
- LED light for illuminating measurement points.
(It turns on/off automatically in relation to the ambient brightness.)
