Kyoritsu KEW 4300 Earth Testers
KEW 4300 is simplified earth resistance tester (based on 2-pole method) that can be used for various distribution lines and electrical appliances and it also can measure AC/DC voltage. (As for AC Voltages, true rms values can be obtained.)
200/2000(2 ranges): auto-ranging.
Warning buzzer triggered at 100or 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.)
Small test current (max 2mA) not triggering RCD.
