If the current oven temperature is less than the set point, the oven begins heating. 8. Press Start to begin the run. If the oven has not reached the set point, there is a delay while the oven heats up or cools down. During this time, the STATUS screen displays OVEN WAIT. When the oven is within 5 °C of the set point, the cell and bottle trays rotate to the first positions and the ASE 300 begins running the first sample. During Method control, the ASE 300 runs samples sequentially until it reaches an empty cell or bottle slot or, if the trays are full, until all samples have been run and the trays are back at positions 1. See Section 2.2 for details about the extraction process. During the run, the status of operating parameters is updated on the CURRENT STATUS screen. After a set time (the default is 20 minutes), and if no keypad buttons have been pressed, an alternate status screen is displayed (see Figure 3-19). To return to the CURRENT STATUS screen, press any button on the front panel keypad. B TTL Figure 3-19.
