98
Probable Cause
Dirty lenses on the Vessel
Module.
The dissolution apparatus is
not supported (i.e.,
non-Agilent/ Varian/VanKel)
or the firmware version on
the dissolution apparatus is
not supported.
Serial-to-USB cable drivers
were not installed properly.
Serial port not functioning
properly.
The magnetic clip is not in
the proper position.
Height arm extension not
seated on bottom middle of
the dissolution vessel. Need
to select the proper pin
height.
Need to use a 1L and/or an
open-head apparatus.
The sampling manifold
and/or evaporation covers
must be removed.
Suggested Solution
• Clean the lenses inside of the
Vessel Modules with a
lens-cleaning cloth.
• Contact Agilent to update the
firmware on the apparatus (if
possible).
• Reinstall the cable drivers, if
necessary.
• Verify status of serial port using
Device Manager (Control Panel >
Administrative Tools > Computer
Management).
• The top of the RPM clip needs to
be slightly above the VM.
"RPM Detection Magnetic Clip
Placement" on page 62..
• Ensure that the height arm
extension is oriented in the center
of the VM. Ensure the proper pin
setting of the VM is selected.
"Height Arm Pin" on page 54..
• Ensure 1L vessels are being used.
• The VM should fit any open-head
design apparatus. The VM will not
fit on a dissolution apparatus with
a closed-head design.
• Remove the manifold and
evaporation covers of your
dissolution apparatus. Please
consult the Operator's Manual of
your dissolution apparatus for
applicable instructions.
