Earth Testers

MODEL 4102A
 
 
4102A
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.

MODEL 4105A
 
 
4105A
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
 
Instruction Manual
 
4300
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.

True RMS
Accurate 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

KEW 4202
 
Product Catalogue Instruction Manual
 
4202

Various useful functions are available on Android devices using Bluetooth communication
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 1200 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
