( As for AC Voltages, true rms values can be obtained.) • 200/ 2000© ( 2 ranges) : auto-ranging. • Warning buzzer triggered at 100© 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.) • Small test current ( max 2mA) not triggering RCD.
