Figure 2: AVS plate showing LED indicator

• Select the Reset function on the Instrument page in ICP Expert (Figure 3).

Figure 3: AVS control section on the Instrument Page

Confirmation: If the AVS LED indicator turns green, the reset was successful and no further actions are needed.

• If the LED remains red or an error message appears, perform a system reset by power cycling the ICP-OES system by following these steps:
  1. Save and close the software
  2. Turn off the PC
  3. Turn off chiller (if on)
  4. Turn off the autosampler
  5. Turn off the instrument by pressing the front button on the bottom left (while facing the instrument) (Figure 4)
  6. Turn off the main power switch on the left side of the instrument (Figure 5) and wait 5 minutes

  8. Select the Instrument page in the software menu
  9. Is the LED on the AVS plate still red? Try resetting via the software again (Fig. 2)
  10. LED on the AVS plate should be green indicating it is ready to use
  11. Chiller can be turned on and the instrument prepared for use

Caution:  If the AVS LED indicator is still red after this process, please verify that installation was performed properly.  If the red LED persists after reinstallation of the AVS valve and tubing and following the preceding steps, please contact Agilent Technical Support or the local Agilent Representative
