5. Operating the device Operating the device The menu structure is illustrated schematically on the following pages. 5.1 Display elements in use After pressing the "MENU" button for > 1.5 s, the first menu item "AL" appears. Use Device front/display Function (Enter) buttons for navigation and settings.
Operating the device Operating the device 5.2 Menu overview 5.3 "AL" menu Measurement display 5.3.1 Response value setting Standard display Menu selection Menu The two parameters that monitor the insulation resistance R , "R1" and "R2", can be found in the response value menu "AL". The value R1 can only be set higher than the value R2. If the insulation resistance R reaches or falls below the values R1 or R2, this leads to an alarm message.
