Calibration error CALIB B (Photometry assay)
In linear (2 to 6-point) or
isozyme P calibration, the
calibration condition is checked
at calculation of parameter K.
This error is indicated if there is
a difference of ±20% or more
between the current and
previous K values.
(ISE)
The calibration concentration or
slope level for display does not
satisfy the following expression.
|Previous value - current value|
(Previous value + current value )/2
×100% > COMPENSATE LIMIT
• Same as in SENS
• Pay attention to
storage method and
the time period of
placement on the
sample disk.
• If the result is
satisfactory,
operation can be
continued. After
measurement,
record parameters
on the maintenance
menu to store the K
value.
Noise error NOISE N (ISE)
This error is indicated if the
difference between the
maximum and minimum
potentials is within the following
range at three of the five
measuring points for each test
(on internal standard or sample).
Na : 0.7mV < |FIV(2) - FIV(4)|
K : 1.0mV < |FIV(2) - FIV(4)|
Cl : 0.8mV < |FIV(2) - FIV(4)|
• Set reagent and
perform ISE priming
(with internal
standard solution
and diluent) once.
• Make sure O-ring is
fitted to each
electrode and its
holder and it is not
fitted doubly.
After reattaching,
perform ISE priming
(with reference
electrode solution).
• Replace the tube
and perform ISE
priming (with
reference electrode
solution) once.
• Clean the waste
solution drain path.
• Clean the syringe
and plunger and
replace the seal
piece.
