Division by zero - Measure = 0
– Check that the optical fibers are well
connected to their holder on the door.
37
Offset out of range
– Ensure that deionized water with
the required degree of purity has been
used.
– If necessary, replace the deionized
water.
– Perform a new zero calibration.
38
Concentration = 0 - calibration
coeff. = 0
– Check that the calibration coefficient is
not equal to zero.
– Make a new calibration.
39
Concentration out of range
– Perform a manual measurement to
check if the analyzer is correctly
calibrated.
40
Division by zero - Concentration
after linearization = 0 or Calibra
-
tion Coeff. = 0
– Check if the calibration coefficient is
equal to zero. In this case, make a new
calibration.
– Check if the final absorbance is equal
to zero. If this is the case, the reaction
has not occurred. Perform the
following steps:
– Check that the reagents are well
injected into the photometer.
– Check that the stirrer turns.
41
Calibration coefficient outside
tolerances (new coefficient
differs from the previous one by
more than 50 %)
– Check that standard concentration
entered at the beginning of calibration
matches the real standard
concentration.
– Check that the standard solution been
prepared and stored correctly.
– Check that reagents are correctly
pumped into the photometer.
– Check that the stirrer turns.
No.
