There are four Status LED’s on the front panel to the right of the concentration display. These LED’s provide a quick view of the instrument’s Status as well as an indication of any problems that may exist. The normal state for these LED’s after the initial 20 minute warm-up period is as follows:

7.2.Front Panel Menus

The M465L has an interactive menu structure that can be operated from the front panel. From within this menu structure, the operator can view real-time parameters such as temperature and pressure, view configuration information, and edit setup parameters such as alarm limits.

Figure 7-2 below shows the menu structure as well as the buttons that are used to navigate it.

Starting with the display in Concentration mode, press CFG to enter Menu mode. At this point the unit-of-measure LED should turn off and the first level of the Menu tree will be active. Pressing the UP/DOWN arrows will now select from the items available at this menu level. Press ENT to enter one of these sub-menus or press CFG to back out of this menu level back to Concentration mode.
