Measurement of the earth electrode resistance
(3-Pole method)
The international standard IC 60364-6 provides information regarding the measurement of the resistance of an earth electrode for TT, TN and IT systems.
This measurement shall be made by the Volt-Amperometric method using two auxiliary earth electrodes. The instrument that covers this requirement is the Earth Tester.
Measurement of the simplified earth resistance
(2-Pole method)
Kyoritsu 4105DL Earth Tester Features:
• 3 pole and 2 pole Earth Resistance measurement (0.01Ω-2000Ω)
• Waterproof design (IP67)
• Rotary Switch makes the user interface very intuitive
• Large LCD Display with Backlight
• Led to monitor correct / non correct auxiliary earth spike resistance
• Earth Voltage Measurement (AC/DC 0-300V)
• CAT Ⅳ – 100V
