Ohmmeters, Low Resistance

Megger’s DLRO10HD enhances its existing family of 10 A DC Low Resistance Ohmmeters (DLRO10 and DLRO10X). This heavy-duty model combines simplicity of operation with selected high power ranges and the ability to simultaneously make measurements and charge the battery from line power. Designed in a rugged case it is equally suited to harsh environments or factory testing. The unit is IP65 rated with lid closed and IP54 when operating from battery power. The lid is removable to facilitate simple connection of test leads. Megger’s DH4 Duplex Handspikes with 1.2 m leads are standard with other lengths and terminations available. This instrument provides significantly enhanced compliance and is capable of delivering 10 A while measuring up to 250 m? and 1 A while measuring up to 2.5 ?. In the high current 10 A modes test current is maintained for up to 60 seconds. The use of a four terminal measurement technique removes the test lead resistance from the measured value. Additionally, before and during a test, test lead contact is monitored to reduce the chance of erroneous readings. The instrument is powered by a rechargeable, sealed lead acid battery, which permits up to one thousand 10 Amp tests to be completed on a single charge. An auto power off function preserves battery life when operating from battery power. The battery contains intelligent circuitry, which prevents damage to the battery from overcharging and charging under extreme temperatures. A degassing safety vent is provided in the unlikely event of the battery degassing during charge. The company also offers cable fault locating system, wm6 insulation & continuity tester, telecommunications insulation tester, industrial insulation testers, insulation & continuity testers, etc.
