Tests: Resistance modewww.megger.comDLRO2 and DLRO2X317. Tests: Resistance modeResistance mode measures the resistance of a unit under test in a forward current direction (unidirectional mode) or forward and reverse direction (bidirectional mode). In manual start mode, the test will be carried out when the TEST button is pressed. In auto start mode the DLRO2 will start the test automatically as soon as continuity is detected, however it will not automatically start testing if continuity is established before the test mode is selected.7.1 Auto-start, bidirectional / unidirectional resistance mode1. Turn rotary switch to select either the auto-start, bidirectional resistance mode position or auto-start, unidirectional resistance mode position. NOTE : To AUTO SAVE results click the SAVE ( ) button now (Refer to 5. Data storage (DLRO2X only) on page 22.).ORResistance test screen appears, ‘Auto-start, Bidirectional Resistance Mode’ or ‘Auto-start, Unidirectional Resistance Mode’ shows in secondary field for a short time then disappears.NOTE : Soft key 1 toggles continuous / single test. Soft keys 2 / 3 cycles through current ratings; default is 2 A, selectable 1 A, 100 mA, 10 mA, 1 mA. In bidirectional, soft key 4 toggles between ‘Display previous 2 results’ and ‘Forward and reverse direction’.2. Select test settings using the soft keys.3. Connect C1-C2 and P1-P2 to the instrument and the unit under test.C and P indicators show red background with for no continuity or green background with for good continuity. When continuity is detected on both circuits, the C and P indicators will both be greyed out and the test will start automatically. If required, to stop the test press the TEST button.
