• The latest circuit design permits the instrument to operate
with the minimum of influence from earth voltage
and earth resistance of auxiliary earth spikes.
• Dust and drip proof. (designed to IEC 529 IP54)
• Earth resistance value can be read directly from the scale.
• Designed to meet IEC 61010-1 safety standard.
• Capable of measuring earth voltage.
• Small and lightweight. Shock resistant new case material.
• 2mA measuring current permits earth resistance tests
without tripping earth leakage current breakers
in the circuit under test.
• Lead wire connection to C and P terminals and proper
auxiliary earth resistance can be checked by "OK" lamp.
Lead wire connection to C and E terminals is good
when "OK" lamp is illuminated.
• Dust and drip proof.(designed to IEC 529 IP54)
• In addition to the facility for precision measurement, test leads for simplified two wire easuring system also supplied as standard accessories.
(unit can be hung from the neck for simplified measurement)
• Designed to meet IEC 61010-1 safety standard.
• Capable of measuring earth voltage.
• Automatic warning when resistance of auxiliary earth spikes is in excess of tolerance.
• Small and lightweight. Shock resistant new case material.
• 2mA measuring current permits earth resistance tests without tripping earth leakage current breakers in the circuit under test.
KEW 4300 is simplified earth resistance tester
(based on 2-pole method)
• 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 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.
Earth Resistance Measurements with 4, 3 and 2 Wires
Earth Resistivity (ρ) Measurement using WENNER method

• Real time measurements can be transferred, shown and saved on Android device (up to 100 measurements)
• Saved data includes measurement, GPS location and date & time
Easy to check on map "When" and "Where" the measurement was made
• Comparator function on Android device informs when the measured value is lower/higher than the preset value
Earth /Ground resistance and Leakage current measurement functions
• The earth resistance from 0.05 to 1500 Ω can be measured without the auxiliary earth spikes in multi-earthing systems
• True RMS leakage or phase current readings from 0.1mA to 30.0A provides vital additional information in earthing networks
• Filter function offers increased immunity to electrical noise and a Noise mark appears in excessively high noisy environments
