Megger DET4 Series Ground Resistance Testers

• 2, 3 and 4 point testing
• Ground voltage range 0 to 100V
• Stakeless (clamp-on) testing
• ART (Attached Rod Technique) capability
• Multiple, user selectable test frequencies
• Resistance measurement range to 200,000Ω
• Simple one button operation
• IP54 rated

Megger DET4 series ground resistance testers include a current measuring function for ART (Attached Rod Technique)
testing capabilities. With this added function, on-site grounds can be tested separately without having to remove the utility connection.
They also provide stakeless testing capability. This method allows the operator to use the instrument like a clamp-on ground tester
in applications where that method is viable, while also being able to operate as a fall of potential tester if required.

The DET4 series can measure resistance from 0.01 ohms to 200 kΩ, a key capability for soil resistivity
testing. Also, to allow accurate testing in noisy environments, the instruments are capable of rejecting noise
up to 40 V peak to peak.

Applications for the Megger DET4 series ground resistance testers:

• Primary and secondary electrical grounding systems
• Utility pole grounds
• Lightning protection systems
• Residential grounds
• Machinery safety grounds
• Computer and communication system grounds
• EMI/RFI system grounds
• Antenna and pedestal grounds
• CATV system grounds
