Description
The Megger DLRO200 is a versatile digital low resistance ohmmeter (DLRO) engineered for precise measurement of low resistances in the micro-ohm range. Utilizing a four-terminal (Kelvin) measurement technique, it effectively cancels the resistance of test leads, ensuring accurate readings. The instrument provides test currents from 10 A to 200 A DC, subject to load resistance and supply voltage, making it suitable for a wide range of applications. Its compact design, weighing less than 15 kg, allows for easy transport and use in various environments. The DLRO200 is equipped with a large LCD screen that displays all test parameters and results, facilitating user-friendly operation. Additionally, it features on-board memory capable of storing up to 300 test results and notes, and an RS232 port for downloading stored results or for real-time output to a printer. The instrument is supplied complete with 5-meter test leads and download software, ensuring comprehensive testing capabilities.
