Available to rent from TechRentals, the Megger DLRO200 is a digital low-resistance ohmmeter that measures resistances between 0.1 μΩ and 1 Ω at high currents. It is used to test circuit breaker and switch contacts, busbar joints and other applications where high current is needed.
The device 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; and in auto mode, once the desired current is selected and leads are connected, it will start testing, suitable for testing busbar joints.
The product provides test currents from 10 A to 200 A DC and includes a 5 m lead set with 2 x 50 mm2 current leads and 2 x potential leads (with clips). It also comes with 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.
