Symptom
Main Unit (TP951) -3
The fluorescence
measurement value (graph)
is abnormal.
(A fluorescence curved line is
unsteady. It falls.)
* Only the cause about the
equipment
is
assumed.
Please also consider the
reagent system.
Filter unit isn't set right.
Set filter unit right.
Abnormality of the filter change
unit.
A replace of the filter change unit or a
control PCB is needed. Make a
request for repair.
Abnormality of a power supply
circuit for LED or a LED light
source
A replace of a power supply circuit for
LED or a LED light source is needed.
Make a request for repair.
The fluorescence
measurement value (graph)
is abnormal.
(The final value of an
amplification curved line is
lower than before.)
* Only the cause about the
equipment is assumed.
Please also consider the
reagent system.
・
A surface of a reagent plate is
dirty.
・
There are wrinkles in a sealing
film.
Fluorescence is detected in a surface
of a reagent plate. Use clear reagent
plates, films and caps, etc..
Brightness of an LED light
source is low.
A LED power supply or a LED has a
problem. Make a request for repair it.
An optical component is soiled.
Resolution of an optical component,
check and cleaning are needed.
Well of the sample block is dirty.
Clean wells of the sample block.

Self-diagnostic Function
・
The rate of temperature heating or cooling is too low.
・
The cycle is too long.
Set the environmental operating temperature to 20-23
℃
and perform the self-diagnostic test.
If out of range, perform the test again.
The test value gets away
from the standard value a
little.
The environmental operating
temperature being used is not
appropriate.
The installation environment must be
within 15 to 30
℃
temperature range.
An air intake and an exhaust port
are closed.
Make sure that the air can ventilate it
sufficiently from a vent.
A cooling fan or a exhaust fan is
no good.
The part needs to be replaced. Make
a request for repair.
On Cycle test, the test value
is too long from standard
value or can
’t get.
The Peltier element or any
temperature sensors are broken.
The sample block needs to be
replaced. Make a request for repair.
