Foreword 9
Maintaining the System
CAUTION
Maintain the system strictly as instructed by this manual. Inappropriate
maintenance may lead to unreliable results, or even equipment
damage and personal injury.
Dust may accumulate on the system surface when the system is
exposed to the outside for a long time. To wipe off dust from the
system surface, use a soft, clean and wet (not too wet) cloth, soaked
with mild soap solution if necessary, to clean the surface. Do not use
such organic solvents as ethanol for cleaning. After cleaning, wipe the
surface with dry cloth.
Switch off all the powers and unplug the power cord before cleaning.
Take necessary measures to prevent water ingression into the system,
otherwise it may lead to equipment damage or personal injury.
Replacement of such major parts as lamp, photometer, sample probe,
mixer and syringe plunger assembly must be followed by a calibration.
Replacement of lamp must be done after the power has been placed
to off for at least 15 minutes.
Samples
CAUTION
Use samples that are completely free of insoluble substances like
fibrin, or suspended matter; otherwise the probe may be blocked.
Medicines, anticoagulants or preservative in the samples may lead to
unreliable results.
Hemolysis, icterus or lipemia in the samples may lead to unreliable
test results, so a sample blank is recommended.
Store the samples properly. Improper storage may change the
compositions of the samples and lead to unreliable results.
Sample volatilization may lead to unreliable results. Do not leave the
sample open for a long period.
Some samples may not be analyzed on the system based on
parameters the reagents claim capable of testing. Consult the reagent
manufacturer or distributor for details.
Certain samples need to be processed before being analyzed by the
system. Consult the reagent manufacturer or distributor for details.
The system has specific requirements on the sample volume. Refer to
this manual for details.
Load the sample to correct position on the sample disk before the
analysis begins; otherwise you will not obtain correct results.
