Product Description

Overview

The Megger Ground Resistance Tester DET3TC is a revolutionary grounding resistance testing instrument that offers convenient on-site testing without the need to disconnect equipment connections.
Versatile Testing Modes
Supports 2-terminal and 3-terminal testing, as well as the Attached Rod Technique (ART). The resistance testing range is 0.01 Ω to 2 kΩ with an automatic-ranging function. The accuracy is 2% ±3 digits for 2-pole and 3-pole testing, and 5% ±3 digits for ART testing.
Adjustable Test Voltage
The test voltage can be adjusted between 25V and 50V, making it suitable for use in residential areas and various electrical environments.
Strong Anti-interference Ability
Can suppress noise up to 40V peak-to-peak, ensuring accurate testing results in high-electromagnetic-interference environments.
User-friendly Operation
Easy to use with simple one-button operation. A large selector switch allows for easy selection of 2- or 3-pole tests, even when wearing gloves. Automatically detects connection and probe status.
Complete Accessories
Comes with test leads, grounding probes, and a sturdy carrying case. An optional interface adapter can be used to match various test leads.
Safety Assurance
Features a safety rating of CAT IV 100V, providing excellent safety protection for outdoor testing. The instrument is IP54 rated dust-proof.
Additional Functions
Includes a voltmeter function to measure ground voltage (0 - 100V, accuracy 2%±2V). Measures leakage current down to 0.5mA when used with the optional current clamp meter ICLAMP.
