10 Result flags Cedex Bio System
List of flags
>Reag Rng
Meaning Absorbance above defined reagent range.
o During calibration, the absorbance value of the lowest calibrator is above the
upper defined range.
Message ID 12
Priority 7
Possible cause Deteriorated or outdated calibrator or reagent.
Recommended actions 1. Check the calibration and reagent expiry dates.
2. Repeat with fresh lowest calibrator.
3. If the flag reappears, replace reagent set (a reagent may be contaminated).
<Reag Rng
Meaning Absorbance below defined reagent range.
o During calibration, the absorbance value of the lowest calibrator is below the
lower defined range.
Message ID 12
Priority 7
Possible cause Deteriorated or outdated calibrator or reagent.
Recommended actions 1. Check the calibration and reagent expiry dates.
2. Repeat with fresh lowest calibrator.
3. If the flag reappears, replace reagent set (a reagent may be contaminated).
> Repl Dev
Meaning Greater than replicate deviation.
Deviation between replicates exceed programmed limit. One or more replicates are
erroneous.
Message ID 13
Priority 12
Possible cause Problems in air/water system, air bubbles, clogged probe.
Recommended actions 1. Check the calibrators for air bubbles and repeat the calibration.
2. If the flag reappears, repeat with fresh calibrators.
3. Check the probe.
4. Check the fluid system.
