DLRO200

DLRO200 is a digital low resistance ohmmeter (DLRO) designed for accurately measuring the resistance of conductors, contacts, and electrical connections in various applications. Here’s an overview of its features and functionalities:

1. Low Resistance Measurement: The DLRO200 is optimized for measuring low resistances typically encountered in electrical systems, such as circuit breakers, busbars, switchgear, and bonding connections. It provides highly accurate readings, even in environments with high electrical noise.
2. High Current Output: The instrument is capable of delivering high test currents, typically up to 200 amperes or more, depending on the model. This high current capability enables the DLRO200 to accurately measure very low resistances with minimal thermal EMF effects and contact resistance errors.
3. Four-Terminal (4-Wire) Measurement: The DLRO200 utilizes a four-terminal measurement method, also known as Kelvin or 4-wire measurement, to eliminate the effects of lead resistance and contact resistance. This ensures precise measurement of the resistance of the test specimen without any errors introduced by the test leads.
4. User-Friendly Interface: The DLRO200 features a user-friendly interface with a clear digital display, intuitive menu navigation, and easy-to-use controls. This simplifies operation and allows users to quickly set up and perform resistance measurements with minimal training.
5. Automatic Temperature Compensation: Some models of the DLRO200 may include automatic temperature compensation (ATC) functionality, which compensates for changes in ambient temperature during testing. This ensures accurate and reliable measurements, even in environments where temperature fluctuations are significant.
6. Data Logging and Storage: The DLRO200 may offer data logging and storage capabilities, allowing users to store measurement results for later analysis and documentation. This feature is particularly useful for recording measurements over time, tracking trends, and generating test reports.
7. Robust and Portable Design: The DLRO200 is designed to be robust and portable, making it suitable for both field and laboratory use. Its rugged construction, compact size, and lightweight design enable easy transport and deployment in various testing environments.
8. Safety Features: The instrument is equipped with various safety features to protect both the operator and the equipment during testing. These may include overcurrent protection, overtemperature protection, and insulation protection, among others.

Overall, the DLRO200 is a versatile and reliable instrument for accurately measuring low resistances in electrical systems. Its advanced features, user-friendly design, and robust construction make it well-suited for a wide range of applications, including maintenance, troubleshooting, and quality assurance in industries such as power generation, distribution, and manufacturing.
