| Description
The Megger DLRO200-115 is a compact, portable digital low-resistance ohmmeter, or micro-ohmmeter, used for precise measurement of very low resistance in a variety of industrial applications. It is well-suited for high-current testing of electrical components such as circuit breaker contacts and busbar joints. |
| Key features
Measurement range: 0.1 µΩ to 1 Ω. Test current: Variable from 10 A to 200 A DC. Best resolution: 0.1 µΩ. Power supply: 100 to 130 V, 50/60 Hz. Output: Filtered direct current output to eliminate magnetic transients. Weight: Less than 15 kg (32 lbs). Ingress protection: IP54 rating, making it suitable for field use. Features Four-terminal measurement: The DLRO200-115 uses the Kelvin or four-terminal measurement technique to cancel out the resistance of the test leads, ensuring high accuracy. Test modes: Normal: Tests resistance by applying the set current for approximately 10 seconds. Auto: Tests resistance automatically when the potential leads are connected. This is convenient for testing multiple joints, such as on a busbar. Continuous: Monitors resistance over a period of time, taking a reading every 2 seconds. Data management: Internal memory stores up to 300 test results with notes. RS232 port allows for data download to a PC or direct output to a printer. PowerDB compatibility for test result storage and management. User interface: Features a large, backlit LCD screen and an alphanumeric keypad for setting test currents, limits, and adding notes to stored results. |
