Megger DET3TC 3-Terminal Earth Resistance Tester

Pick the Megger DET3TC when the earth electrode has to stay bonded. ART, the attached-rod method, uses the optional ICLAMP so you can read that rod without opening the connection. A disconnected electrode still uses the ordinary 3-pole test. On Megger’s DET3 contractor data, 2-pole and 3-pole accuracy is 2% ±3 digits, while ART is 5% ±3 digits. The meter rejects noise up to 40 V peak to peak and tests at 128 Hz. Earth voltage runs from 0 to 100 V.

MME is an authorized Megger representative in the UAE. See the Megger range and earth resistance testers. For four terminals and soil resistivity with ART, compare the Megger DET4TC2 or the rechargeable Megger DET4TCR2. A stake-free clamp check is the Megger DET24C. Stake testing versus a clamp is covered in Fluke 1625-2 vs Megger DET4TCR2.

Megger DET3TC questions

What decides this tester on a connected earth:

• Use ART when the bond must stay on. Use 3-pole when the electrode is already open.
• ART needs the optional ICLAMP. Confirm whether the stake kit is in the box you are ordering.
• If the display flags the C or P spike, reset that stake before you trust the ohm reading.

Megger DET3TC 3-Terminal Earth Resistance Tester

The Megger DET3TC allows a wide range of earth-testing methods — 2-pole, 3-pole and no-disconnect testing (ART) — plus resistance and voltage measurement. During each test it automatically evaluates and displays the status of the connected current (C) and potential (P) spikes, so problems such as high spike resistance or interference are flagged before they affect the result. With a 0.01 Ω to 2000 Ω range, selectable 25/50 V output and CAT IV 100 V safety, the DET3TC is a dependable tester for earthing systems.

Key features of the Megger DET3TC

What the Megger DET3TC shows you on a stake test:

• 2-, 3-pole & ART testing – fall-of-potential plus no-disconnect (ART) stakeless testing with the optional ICLAMP.
• 0.01–2000 Ω range – earth-resistance measurement with 2% ±3 digit accuracy.
• Automatic spike checks – C and P spike status automatically evaluated and displayed.
• Selectable output – 25 V or 50 V test voltage; earth-current 0.5 mA–19.9 A with ICLAMP.
• CAT IV 100 V, IP54 – rugged, weatherproof design for site use.
• Portable – 8 × AA with battery status bar; 1 kg.

Megger DET3TC applications

Jobs this 3-terminal earth tester is built for:

• Fall-of-potential (3-pole) earth-electrode resistance testing.
• No-disconnect (ART) stakeless testing of multi-grounded systems.
• General earthing-system maintenance and verification.

What’s in the box – Megger DET3TC

What to confirm is in the Megger DET3TC kit:

• Megger DET3TC earth resistance tester
• Batteries (8 × AA)
• Carry case and documentation (test leads/spikes per kit)

ART testing requires the optional ICLAMP; earth-test lead/spike kits are ordered separately or as a kit — confirm with MME.
