(
Alarm Name
ADC abnormal
Sample short
Noise error
Level error
Sample value abnormal
Calculated disabled
The result of ADC is abnormal. (Checked in ADC task)
Sample volume is inadequate. (Checked in control task)
This alarm is issued when a difference between maximum and minimum
potential values at three out of five measurement points in each test is within
the following range (on internal standard and sample).
Na : 0.7 mVFIV (2) - FIV (4)
K : 1.0 mVFIV (2) - FIV (4)
Cl : 0.8 mVFIV (2) - FIV (4)
This alarm is issued when a difference between maximum and minimum
potential values at three out of five measurement points in each test is within
the following range (on internal standard).
-90.0 mV ≤ EAV ≤ -10 mV
Na :
-90.0 mV ≤ EAV ≤ -10 mV
K :
100.0 mV ≤ EAV ≤ 180.0 mV ⇒ OK
Cl :
The sample concentration (C(S)) is within the following range.
Na : C (S) < 10 mEq/L or C (S) > 250 mEq/L
K : C (S) < 1 mEq/L or C (S) > 100 mEq/L
Cl : C (S) < 10 mEq/L or C (S) > 250 mEq/L
Due to zero division, log-X, etc.
