Megger DLRO10X: Smart Low-Resistance Testing with Precision, Control, and Data Storage
Discover why the Megger DLRO10X is a powerful choice for low-resistance measurements in manufacturing, maintenance, and industrial testing—built for accuracy, speed, and professional workflow control.
What Is the Megger DLRO10X?
The Megger DLRO10X is a fully automatic low-resistance ohmmeter designed to measure resistance from
0.1 μΩ to 2000 Ω using test currents of up to 10 A DC. It is built for users who want both
automation and manual control, making it ideal for repetitive production testing and demanding field applications.
Unlike standard automatic instruments, the DLRO10X includes a two-axis paddle menu for manual control,
real-time download, on-board storage, and advanced testing features such as
high/low pass limits and unidirectional measurement mode.
Key Features of Megger DLRO10X
⚙️
Manual Control with Two-Axis Paddle
Select the maximum test current manually and fine-tune the measurement process with greater control.
💾
On-Board Storage
Store test results and notes directly on the instrument for later retrieval and reporting.
📡
Real-Time Download
Transfer measurement data in real time via RS232 for efficient documentation and analysis.
✅
Go/No-Go Testing
Set high and low pass limits for quick quality checks in production and maintenance workflows.
↔️
Forward/Reverse Reading
Displays forward and reverse measurements as well as the average of the two for better confidence.
🚀
Fast Results
Average readings can be displayed in as little as 3 seconds, helping speed up testing cycles.
Typical Applications
The DLRO10X is widely used wherever accurate low-resistance measurement is critical. Common applications include:
Switch and contact breaker resistance
Busbar and cable joints
Aircraft frame bonds and static control circuits
Welded joint integrity
Battery inter-cell connections up to 600 V peak
Transformer and motor winding resistance
Rail and pipe bonds
Wire, cable, and composite resistance
It is also ideal for repetitive testing in manufacturing environments and production lines.

Why DLRO10X Stands Out
The DLRO10X is more than a low-resistance meter. Its manual control, data storage, and pass/fail limits make it a strong
fit for users who need repeatable results and easier workflow integration.
