2.1.2 Measurement and Calibration
This instrument is capable of 4 types of measurements: normal measurement and STAT
measurement for measuring patient samples, control measurement made to maintain measurement
precision, and check measurement for checking to see that the instrument is working correctly.
■ Normal measurement
Normal measurement continuously measures a number of samples loaded in the sample racks.
A sample rack can contain up to 10 samples. Place the sample racks with samples in the sampler
and press the start key. The instrument then automatically transports the sample racks, aspirates
the samples in order, and obtains the results. Up to 5 sample racks (50 samples) can be loaded
into the sampler for one-way transportation, and up to 10 sample racks (100 samples) for loop
transportation. For identification purposes, the results are given under serial measurement numbers,
port numbers, and ID numbers from barcodes.
* The instrument is factory-set to the one-way transportation mode. If you prefer loop transportation to measure more
samples at a time, contact your distributor.
* For more information about measurement numbers and rack-port numbers, see the next page.
■ STAT measurement
STAT measurement is used to interrupt ongoing normal measurements and measure one or more
urgent samples. There are two types of STAT measurements:
Port STAT measurement: Measures a single sample loaded into the STAT port. If you have
a sample to test urgently, you can load the sample into the STAT
port to interrupt normal measurements in progress.
Rack STAT measurement: Interrupts normal measurements in progress to measure up to 7
samples loaded into the STAT and control rack.
■ Control measurement
The specified controls should be measured at regular intervals to maintain the precision of the
instrument. Use the STAT and control rack to load the controls. Up to 3 types (or 3 concentrations)
of controls can be used at a time.
■ S.G. calibration
S.G. calibration is for calibrating the instrument using two types of S.G. standard solutions (low
and high solutions) that the operator prepares. It is recommended to perform S.G. calibration once a
month.
■ Check measurement
If you suspect there is something wrong with obtained results, use the supplied check strips to
check if the instrument is working correctly.
