Error text
Explanation / Cause
Solution
Measure blank first
No blank has been measured
for the method selected.
Measure the blank.
Measure standard first
No valid calibration
for the method selected.
– Measure standards.
– Program a different calculation
(fixed factor or direct absorbance
measurement).
not within calibration
(For calculation via
non-linear regression only:)
The sample result is not within
the calibration range.
Repeat the measurement
(dilute sample if necessary).

Error text
Explanation / Cause
Solution
No STD method
The
measuring key was pressed
although "Standard" was not programmed
as a procedure for the method selected.
– Re-measure the methods without
standard request.
– Program the "standard"
calculation.
Measured values
not plausible
(For one-point calibration:)
Absorbance measured is 0 A.
Re-measure standard.
(Prepare again if necessary).
Measured values
not monotonous
(For multiple-point calibration:)
The measured values do not produce
monotonously rising or falling sequences.
Check standards and re-measure in
the correct sequence (ascending
concentration).
Calibration curve is not
monotonous
(For non-linear regression:)
The calculated curve is not monotonous.
Check standards and re-measure in
the correct sequence (ascending
concentration).
Standard
