(5) ISE Calibration Alarm Check
Alarm Name Alarm Check Method (alarm setting condition)
Standard error Calibration is invalid.
(Any of the following alarms has occurred; ADC abnormal, sample short,
calculation disabled, noise error and level error.)
Slope abnormal (1) The slope for display is within the following range.
Na, K : Slope < 45.0 mV
Cl : Slope > -35.0 mV
(2) Electrode response is degraded (carry-over ratio is as given below).
Na : 0.232 < A
K : 0.160 < A
Cl : 0.490 < A
ISE prepare (1) The slope for display is within the following range.
Na, K : 45.0 mV Slope 49.9 mV or
68.1 mV Slope
Cl : -39.9 mV Slope -35.0 mV or
-68.1 mV Slope
(2) Electrode response is degraded (carry-over ratio is as given below).
Na : 0.154 < A
K : 0.107 < A
Cl : 0.330 < A
Internal standard
concentration
abnormal
The concentration of internal standard solution (C(IS)) is within the following
range.
Na : C (IS) < 120.0 mEq/L or 160.0 mEq/L < C (IS)
K : C (IS) < 3.0 mEq/L or 7.0 mEq/L < C (IS)
Cl : C (IS) < 80.0 mEq/L or 120.0 mEq/L < C (IS)
Calibration
abnormal
On each of the calibrator concentration and slope for display, the previous and
current values are compared and the result exceeds the COMPENSATE LIMIT
value.
× 100 (%) > COMPENSATE Limit
Previous value - Current value
(Previous value + Current value)/2
