Please note that this version of the Megger DLRO200 comes as standard without test leads. For the full kit including these, please see the Megger DLRO200 standard tester.
Megger's DLR200 is designed to make measurement and datalogging of low resistance levels as simple as possible.
Capable of measuring resistance levels between 1μΩ and 1Ω, the DLRO200 uses test current from 10A to 200A to measure the level of resistance generated across a conductor. Measurements are carried out using four terminals, a testing procedure that negates the resistance of test leads and ensures that measurements taken are as accurate as possible.
Three different measurement modes are available on the DLR200: continuous, normal and auto. In continuous mode, resistance levels can be measured over a period of time as the tester constantly generates a current. In normal mode, standard testing is applied, ramping up the desired level over ten second. The third mode, auto, is used for repeated testing and makes it easy to generate the correct current for a test.
Up to 300 records can be stored directly on the DLRO200's built-in memory and can be downloaded easily to PC/printer via an RS232. A alphanumerical keypad can be used to add notes to stores results or easily navigate between stored data.
