SIP -W Waste Container
LCD that is covered with a touch-sensitive film ("touch
screen").
SIP abbr. for sample inlet path
S1 Rinse Solution To rinse the system.
S2 Fluid Pack Calibration solutions for BG and ISE.
S3 Fluid Pack A Calibration solutions for Glu, Lac,
Urea/BUN.
SO
2
Oxygen saturation.
Status messages These messages define causes that
affect the measurement values and/or calibration values
of the analyzer.
System calibration Every 8, 12 or 24 hours (default)
which includes Wavelength calibration of polychromator,
cleaning with internal cleaning solution, Automatic
conditioning of the Na
+
electrode (every 24 hours),
Calibration of the mixing system and the
2 point calibration of all parameters.
System stop This error creates a window outlined in
red halting the analyzer, the instrument stops.
System warning Only a warning whithout any action.
T&D module The T&D (Turn & Dock) module is used
for sample input and for aspirating in solutions from S1,
S2, S3 and the QC material from the AutoQC module. A
comprehensive tube system allows quick and accurate
distribution of the different fluids.
It consits of the T&D disk and tubing, sample container
detection, sample inlet path (SIP) and fill port holder
with fill port.
Tension lever Peristaltic pump's clear plastic cover.
tHb calibrator calibration solution with known tHb
value to calibrate the COOX modul.
tHb/SO
2
module The tHb/SO
2
module is an optical
sensor module for determining the levels of total
hemoglobin (tHb) and oxygen saturation (SO
2
) in whole
blood.
Tonometered whole blood Whole blood was
tonometered at 37 °C to various levels of gravimetrically
prepared gases with CO
2
and O
2
concentrations certified
to ± 0.03% absolute by the manufacturer. Expected and
observed values for PCO
2
and PO
2
were corrected to
760 mmHg.
Urea (lat. Urea Pura) Urea is the most important
catabolic product of the protein metabolism. It indicates
a limited or insufficient kidney function (reduced or
nonexistant filtration in cases of shock, heart failure,
hypertonia, dehydration, tumours, etc.).
Vacuum pump The vacuum pump is responsible for
washing and drying the tubes (with the exception of the
measuring channel) and for aspirating calibration
solutions over the T&D module.
Valve V19 Air mixture valve.
Valve VM Mixing valve for calibration solutions A
(CAL A) and B (CAL B) from the S2 Fluid Pack.
Volume limitation Is the maximum volume of sample
which is aspirated from the container.
W Waste Container Waste water.
