Megger DLRO10 Ducter Ohmmeter + DH4-C
£4,075.00
The Megger DLRO10 is a 10A digital low resistance ohmmeter designed for fast, dependable four-terminal measurements on busbars, switchgear, cable joints, and wound components. It automatically selects the appropriate test current up to 10A and measures from 0.1 microohm to 2000 ohm across seven ranges. Automatic forward and reverse current cancels standing EMFs, and the instrument checks continuity on the potential and current leads to prevent bad connections from skewing results. Compact and portable with a rechargeable battery module, the DLRO10 with DH4-C duplex handspikes is ideal for field and workshop use.
Megger DLRO10 Ducter Ohmmeter + DH4-C
Megger DLRO10 Ducter Ohmmeter + DH4-C Digital Low Resistance Ohmmeter, 10A, Battery & Mains Power, Hi/Lo Output, Memory Storage, USB Download, UK (BS1363) Mains Plug, Connect Duplex Handspikes 1.5m Test Leads (x2). where needed and averaging forward and reverse readings to remove thermal EMFs. Continuity checks on the P and C circuits reduce the risk of high contact resistance errors, and the clear display makes on-site work straightforward. The DH4-C duplex handspike leads support true four-wire measurements for low resistance joints and bonds.

Megger DLRO10 Ducter Ohmmeter FAQs
What is the difference between DLRO10 and DLRO10X.
Both measure 0.1 microohm to 2000 ohm with up to 10A. DLRO10X adds manual current control, onboard storage, and download options.
Why does the instrument reverse current during a test.
Reversing and averaging cancels thermal EMFs present at the test piece, improving stability and accuracy.
Do the DH4-C handspikes support four-wire measurements.
Yes, the duplex handspikes provide separate current and potential contacts for true four-terminal testing.
How often should the DLRO10 be calibrated.
Most users choose six to twelve months depending on usage, environment, and quality system requirements.
Is it safe to connect to live circuits.
No. As with all low resistance testers, ensure circuits are de-energised and discharged, and observe CAT III 600 V safety limits.
