Calibration and Absorbance Linearity
Each instrument is calibrated during manufacturing using standards that are traceable to the
National Institute for Standards and Testing (NIST), and is tested to verify its linearity to 2A.
This preset calibration is very stable. Absolute calibration can be verified with the use of NIST
filters, or by periodic comparison to a reference instrument that is known to be calibrated to
NIST filters. Calibration may be confirmed using a commercially available calibration check set
which can be obtained from your distributor. A periodic verification of instrument linearity is
advised. Since most lab test results are based upon standards rather than upon absolute
absorbances, the linearity of the instrument is the more critical indicator of instrament
performance.
CAUTION
DO NOT ALTER ANY POTENTIOMETER SETTINGS !
Changing these settings will make the factory calibration
data invalid.
In the unlikely event the calibration data is lost or corrupted,
the absorbance factor is set to 1.000 and the temperature
offset adjustments for the block and cell are set to 0,0.
Do not enter values other than those recorded on the calibra-
tion label unless absolutely necessary.
