Table 7 Critical errors (continued)
Error
Possible cause
Hydraulic
The hydraulic pressure
pressure for
source is not sufficient.
online sampling
is not sufficient
High pressure
An internal hydraulic
found
regulator failure occurred
or the adjustment setting is
out of tolerance.
Low pressure
The external pressure
source is not sufficient.
The pick-up tube cap is
installed.
Pressure
The external pressure was
dropped to a
decreased during the
level that is not
sample test.
sufficient
The sample fluid viscosity
is too high. (PODS only)
There is an internal
hydraulic regulator failure
or adjustment setting that
is out of tolerance.

Solution
Make sure that the fluid pressure
is more than 40 psi for all of the
sample period. Make sure that
there are no leaks on the online
adapter O-ring.
Contact technical support.
Make sure that the external air
source is stable and set near
100 psi. Decrease the flow rate,
especially with high viscosity
fluids. Make sure that there are
no leaks on the sample cup O-
ring.
Remove the pick-up tube cap.
Make sure that the external air
source is stable and set near
100 psi. Decrease the flow rate,
especially with high viscosity
fluids. Make sure that there are
no leaks on the sample cup O-
ring.
Decrease the flow rate or dilute
the sample with a suitable clean,
filtered and miscible fluid that will
decrease the sampling viscosity
to within the range of the counter
(10–424 cSt).
Contact technical support.
Table 8 Non-critical errors
Error
Possible cause
SNSR FLOW
There is a blockage in the
CELL ERROR
sensor cell within the view area
and the detector does not see
the laser light.
The amount of sample fluid is
not sufficient.
The sensor is out of calibration.
This results in a low signal.
The sample is contaminated
with water or high particle
contamination.
The laser or sensor electronics
failed. (GlyCount only)
Solution
Do the cell cleaning
procedure as described in
Remove the flow sensor
blockages
on page 18.
Add more sample fluid.
Return the unit to the factory
for calibration or repair.
Remove the water or try
another sample. If the
sample is highly
contaminated, dilute the
sample.
Return the unit to the factory
for calibration or repair.
