Description
Calibration State
Displays the standard currently being measured during the calibration cycle (for example, Measuring
Low, Measuring High).
Percentage Complete
A 'real-time' indication of how far through a calibration is.
OD, Low/High
The measured Optical Density (OD) of the low standard and high standard of the previous calibration.
Current Value
The raw signal from the analyzer detector shown as a voltage (0 to 4095 mV) and also converted into
a concentration value. This value is displayed only for the high standard and after the addition of all
reagents.
Last Gradient
Displays the calibration gradient of the previous calibration.
Gradient Coefficient
The gradient coefficient is an indication of the difference between the calculated calibration gradient
and an ideal calibration gradient stored within the analyzer.
Any slight differences (due to temperature variations, reagent ageing etc.) are expected and
'calibrated out'.
If there is a large variation, the analyzer fails calibration. The ideal coefficient =1, default fail criteria
occurs when the coefficient is outside the range 0.4 to 1.6.
Time Last Cal.
The date and time of the previous calibration.

Sample 1 to 3
Displays the level sensor reading from the side sample pot (empty or OK).
Reagent 1 to 3
Displays the level sensor reading from the reagent level sensors (empty or OK).
DI
Displays the level sensor reading from the de-ionised water reagent sensor (empty or OK).
Standard
Displays the level sensor reading from the calibration standard reagent sensor (empty or OK).
