7.2 Optimizing for Maximum Performance
The instrument has been fully factory tested to ensure that its performance is
within the specified limits.
Experience has shown that operating technique and laboratory conditions cause
the greatest amount of inaccuracy.
The greatest accuracy can be obtained from the instrument by observing the
recommendations below:
7.2.1 Instrument Location
The instrument should be placed on a level, flat surface that is free from dust,
solvents and acidic vapors.
The instrument must be protected from vibrations and direct light, particularly
sunlight.
When performing the measurements, always close the plate support cover to
ensure that the results are not effected by any external light.
7.2.2 Operating Procedure
General
1. The best repeatability is obtained, when the measurement wavelength
corresponds to the maximum absorbance wavelength of the particular
solution.
It is important to use the maximum absorbance wavelength, if the
absorbance curve of the sample is over a narrow wavelength band.
2. After each microplate has been measured, please refer to the test kit
package for information regarding the validation procedure.
3. When very accurate results are required, ensure the Accurate
measurement mode is used.
