The DLRO200-115 Ohmeter is specifically designed to check and measure contact resistance in high-voltage circuit breakers, disconnecting switches (isolators), busbar joints, or any other low resistance measurement.

Highly accurate and versatile, this instrument can measure resistances ranging from 0.1 uOhm - 1 Ohm, even at high currents. It also provides test currents from 10 A up to 200 A, depending on the load resistance and supply voltage.

For applications requiring a smooth DC current, the DLRO200-115's extra filtering on the output reduces mains frequency ripple. It can even drive 200 A through a total current loop resistance of 11 milliohms. Its filtered output eliminates magnetic transients that could inductively trip a breaker's control (bus differential relay) if left in the test circuit.

Remarkably compact and lightweight, the DLRO200-115 weighs less than 32 lbs (15 kg) making it easy to transport and use in a variety of settings. It can shift from workshops and production floors, to field use with its water/dust ingress rating of IP54, ensuring it can withstand harsh environments. Test on the go and retrieve later, as many as 300 sets of results may be stored in the test set's on-board memory for future download to a PC or sent to a printer through its RS232 port.
