The Megger DLRO200-115 Digital Low Resistance Ohmmeter measures resistances between 0.1 microohm and 1 ohm, at high currents. This versatile instrument can provide test currents from 10 amps up to 200 amps subject to the load resistance and supply voltage. A large liquid crystal display provides all the information needed to perform a test; all test parameters and measurement results are displayed.

The unique design allows the weight and size of the DLRO200-115 to be kept to a minimum; the instrument weighs less than 33 lbs. This small size makes the DLRO200-115 equally suitable for applications in the workshop, on the production floor or in the field. The high current capability and compact design make the DLRO200-115 suitable for testing circuit breaker contacts, switch contacts, busbar joints or other applications where high current is needed.

300 sets of results may be stored in the on-board memory for later download to a PC or may be output directly to a printer via the RS232 port. User may also add notes to any stored result by using the on-board alphanumeric keypad, thereby making later identification of results straightforward.

As well as adding notes to stored results, the alphanumeric keypad allows you to set the test current directly by typing in the value required. The DLRO200-115 will check the continuity of the test circuit, and will quickly ramp the test current up to the desired level. The keyboard is also used to set upper and lower limits for the result and to prevent the use of excessive currents by setting an upper limit to the allowable test current.

The DLRO200-115 uses a four terminal measurement technique to cancel the resistance of the test leads from the measurement. It operates in one of three modes, which are simply selected from the on screen menu.
