The detector is turned on but has not yet downloaded the
operational file from the data system computer.
Communication to the data system PC has been
established.
There is no communication with the data system.
The detector is ready for a run.
A run is in progress and the detector is sending data to the
data system computer.
The PDA detector is not ready to start a run for one of
these reasons:
• A valid method has not been downloaded (following
power on).
• Both lamps are off, or one of the lamps is failing to
turn on.
• The lamp or wavelength calibration is not valid.
The PDA detector is in an error state while in the
Run mode.
One or both lamps are turned on.
The lamps are off or the D2 lamp is starting. The
D2 lamp takes approximately 30 seconds to turn on.
