Megger DLRO200-115 Ohmmeter

Megger DLRO 200-115 Digital Low Resistance Ohmmeter

The Megger DLRO200-115 Ohmmeter is designed to check and measure contact resistance in high voltage circuit breakers, disconnecting switches (isolators), busbar joints, or for any low resistance measurement. The test set accurately measures resistances ranging from 0.1 Microohm to 1ohm, at high currents.

The Megger DLRO200-115 is a versatile instrument that can provide test currents from 10 amps up to 200 amps, subject to the load resistance and supply voltage. For those applications that demand a smooth DC current, the DLRO200-115 has extra filtering on the output to reduce mains frequency ripple and can drive 200 amps through a total current loop resistance of 11 milliohms. The filtered output of the DLRO200-115 also eliminates magnetic transients that could inductively trip a breaker s control (bus differential relay), if left in the test circuit.

The unique design allows the weight and size of the Megger DLRO200-115 to be kept to a minimum; the instrument weighs less than 32 lbs. (15 kg). This small size plus a water/dust ingress rating of IP54 makes the test set equally at home in the workshop, on the production floor or in the field.

300 sets of results may be stored in the Megger DLRO200-115E Digital Low Resistance Ohmmeters on-board memory for later download to a PC or may be outputted directly to a printer via the RS232 port. You may also add notes to any stored result by using the on-board alphanumeric keypad, thereby making later identification of results easier to determine.
