new simplified earth tester
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.)
• 200/2000ω (2 ranges): auto-ranging.
• 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 卡塔尔世界杯中国足球赛事
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.
