The notes below will require some TVOC spares:
Next thing to try is to replace the pellet with another one if available and switch the instrument on to check
(remembering that the instrument should be left on for a few minutes if F1 appears straight away).
If the instrument still shows this error then the lamp should be replaced if available and then the PID cell
should be replaced after if it is still not cured.
If you do not have any spare pellets, lamps or PID cells then you will need to contact Ion Science for some
assistance if the problem remains after the in strument has completed a few minutes of run cycles and the
cable has been checked. Or alternatively if the problem remains after you have tried replacement parts.
___________________________________________________________________________
If an F2 error is shown on screen this generally means that ambient light is getting to the light sensor on the
sensor board.
This may be because the metal cap and PID cell have been removed from the instrument while main power
is still on or that the PID sensor has been left out when the cap has been screwed back on.
By replacing the cap and the sensor this error should go away.
In the event that the sensor and cap are both on the instrument and yet F2 is still on the display please
contact Ion Science for some assistance.
