• 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.

• 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.

• Advanced Filtering method (based on FFT Fast Fourier Transform) reduces noise interference for obtaining stable measurements.
• Automatic and Manual selection of the Test Current Frequency in four bands (94/105/111/128Hz). In Automatic mode, KEW 4106 will select the most suitable Frequency.
• Several sub-results can be shown on the display: Resistance of the Auxiliary Earth Spikes, Frequency of Test Current, Voltage and Frequency of Interference (noise), Residual Resistance Rk, etc.
• Warning for excessive noise and high Auxiliary Earth Spikes resistance.
• Large Graphic Display with backlight for readings in poorly illuminated areas.
• Up to 800 measurement results can be saved in the memory and recalled on the display.
• The stored results can be transferred to a PC using the "KEW Report" software and a USB adaptor (Model 8212-USB) which are included.
• Robust design with IP54 protection.
• Custom microprocessor controlled for highest accuracy and reliability.
• 3 LEDs for checking correct wiring status.
• 15mA LOOP measurement:
LOOP impedance 2000Ω range measurement is carried out with low test current (15mA).
The current will not cause tripping out involved RCD even the one with the lowest nominal differential current (30mA).

A function to detect current, which effects on an earth resistance measurement and display "NOISE" mark on the LCD.
• Memory function
Save and display up to 100 measurement data.
• Data hold function / Buzzer function / Back light function
• Compliant with Safety Standards of IEC 61010-1 : CAT IV 300V Pollution degree2
Note:
A single earthing can not be measured. (Only for Multiple Earthing System)
• 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
• 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.
