When testing for electrical problems in various types of equipment, a low resistance ohmmeter will locate most issues. The versatility and usefulness of low resistance ohmmeters make them a preferred tool of technicians in a broad range of residential, commercial and industrial applications.
An ohmmeter tests the resistance that a circuit has to the flow of an electrical current. Resistance is measured in ohms. The higher the ohms, the more resistance the circuit has to the current flow. If a circuit has zero ohms, current will flow freely whereas with infinity ohms, current cannot flow at all.
Providing significantly enhanced compliance the Megger DLRO10HD 10A Digital Low Resistance Ohmmeter is capable of delivering 10 A while measuring up to 250 mΩ and 1 A while measuring up to 2.5 Ω.
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.
