Available to rent, the Megger DLRO200 is a digital low resistance ohmmeter that measures resistances between 0.1 µΩ and 1 Ω at high currents.
The microhmmeter can operate in three modes. In ‘continuous’ mode it will monitor a resistance over a period of time. In ‘normal’ mode it will test a current at the push of a button. In ‘auto’ mode, once the desired current is selected and leads are connected, it will start testing - which is suitable for testing busbar joints.
It is also suitable for testing circuit breaker and switch contacts and other applications where high current is needed.
It features test currents from 10 A to 200 A DC, onboard memory for up to 300 test results and notes, and an RS232 port to download stored results or for real-time output to a printer.
