Troubleshooting
NOTE: Troubleshooting as described in this chapter should be performed only by a qualified
service engineer.
Problem
Possible Cause
Corrective Action
During Oil Analysis
The results obtained for
one or more properties are
unacceptable.
The oil type entered during
'Prepare Run' is incorrect.
Ensure the correct oil type has
been entered.
The cell pathlength may not
be correct.
Calibrate the flowcell (see
on page 66).
The flowcell may be dirty or
have a build-up of material on
the windows.
Clean the flowcell (see
Maintenance of the Flowcell
on
page 87) and record a
spectrum of the empty cell to
ensure that it is clean. Ensure
the pathlength is calculated
correctly.
The oil may not be
representative of the whole
sample.
Ensure that the portion
sampled was collected roughly
halfway through the filtration
process.
Syringe Pump and Tubing
Syringe pump is not
pumping or stalls.
Syringe pump or tubing is
blocked.
Flush out the syringe pump (see
page 77).
Flush out the fluid system, (see
on page 79).
Loss of air gap due to tubing
blocked, kinked or split.
Replace the defective tubing
(see
on
page 85).
Lead Screw Encoder may be
dirty.
Clean Lead Screw Encoder with
on page 78).
Needle and Wash Port
Cannot align needle.
Call for a PerkinElmer Service
Engineer.
Needle dirty or blocked.
Residues from samples may
be deposited in the needle.
Flush the needle using the
Autosampler controls in the
OilExpress software.
Sample spraying above
transfer/wash port.
The needle is not aligned.
Align the needle (see
on page 60).
The waste tubing is in the
waste, causing a back-
pressure.
Empty the waste container
and/or raise the tubing out of
the waste (see
on page 79).
