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 measuring 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) 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 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 & Resistivity Tester High test current up to 80mA yielding resolution of 0.001Ω on 2Ω range. • 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.
Earth Clamp Tester The earth resistance from 0.05 to 1200Ω can be measured without the auxiliary earth spikes.(The Multiple Earthing System.) • True RMSAccurate true RMS readings of AC current including distorted waveform from 1mA to 30.0A • Noise Check Function 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)
