Description

The Megger DLRO 200 is a digital low-resistance ohmmeter that injects up to 200 A DC for measuring contact resistance in circuit breakers, transformer tap changer contacts, and electrical joints. It uses the four-wire measurement technique to eliminate test lead resistance from results. The DLRO 200 is a flagship Megger instrument for accurate micro-ohm measurements in high-voltage substation maintenance.
