The Megger DLRO200 is a high-performance 200A micro-ohmmeter designed for precision resistance measurements in demanding industrial environments.
Measurement Range: 0.1µΩ - 1Ω with test current range from 10A to 200A DC.
Optimal Resolution: High-precision measurement with 0.1µΩ resolution.
Data Storage: Internal memory for up to 300 sets of results and annotations.
High-Res Display: Backlit LCD showing all parameters and results clearly.
Operating Modes
Normal Mode
The test current rapidly rises to the set value, remains for 2 seconds, and then decreases. Process takes approx. 10 seconds.
Automatic Mode
Set the current and connect test leads; the test begins automatically upon connecting the voltage test leads.
Continuous Mode
Injects current continuously, measuring voltage every two seconds until stopped by the user or circuit disconnection.
