ISE PREP. 92 1 WARNING Upon calibration, the slope
value is within the following
range.
Na : 45.0mV ≤ Slope value
≤ 49.9mV or
68.1mV ≤ Slope value
92 2 WARNING K : 45.0mV ≤ Slope value
≤ 49.9mV or
68.1mV ≤ Slope value
92 3 WARNING Cl : -39.9mV ≤ Slope value
≤ -35.0mV or
-68.1mV ≥ Slope value
4181 to
4183
ISE SLOPE 93 1 WARNING (1) In the result of
calibration, the slope
value is within the
following range.
(2) The response
characteristic of
electrode is poor (in case
carry-over rate (A) is as
indicated below).
Na : (1)SLOPE < 45.0mV
(2)0.232 < A
Refer to alarm
codes 92-1 to 3.
93 2 WARNING K : (1)SLOPE < 45.0mV
(2)0.160 < A
Same as above
93 3 WARNING Cl : (1)SLOPE < -35.0mV
(2)0.490 < A
Same as above
4191 to
4193
ISE I.STD 94 1 WARNING The concentration of internal
standard solution (C(IS)) is
within the following range.
Na : C(IS) < 120.0mEq/L or
160.0mEq/L < C(IS)
(1) Replace STD
and carry out
calibration
again.
(2) Replace the
internal
standard
solution.
94 2 WARNING K : C(IS) < 3.0mEq/L or
7.0mEq/L < C(IS)
Same as above
94 3 WARNING Cl : C(IS) < 80.0mEq/L or
120.0mEq/L < C(IS)
Same as above
(cont’d)
•Make sure that the
standard solution
and reagent are set
properly.
•Make sure that the
standard solution is
free from
concentration or
deterioration.
•Make sure that the
electrodes (Na, K,
Cl) are within their
guaranteed life.
