Calibration
8.1.2 Execution primary calibration
8.1.3 Execution manual calibration
A primary calibration is carried out at the factory and is used as a reference for all following
calibrations.
In general, this type of calibration does not need to be repeated unless important changes
have been made to the analyzer.
Important Note: If you feel that a primary calibration is required, please discuss this with your
Hach Lange representative for advice and assistance before performing this type of calibration
on your analyzer.
The primary calibration sets the slope and zero references. All results of further manual or
automatic calibrations will be compared to the zero and slope references set by this
calibration. Large differences will signify an error in the calibration and will be highlighted with
an error message.
The calibration of the slope is defined first, followed by the zero.
Press Esc to abort the calibration and return to the CALIBRATION menu.
The calibration is made in the following stages:
• Sample preparation
• Conditioning
• Measurement
• Rinse
A bar graph indicates the calibration progress.
At the end of the calibration, the results are displayed on
screen.
Primary calibration results:
S = value of the slope (ppb / Abs)
O = value of the zero shift in milli-Abs
The default values show a general idea of the standard values
according to the analyzer range (0-1000 or 0-5000 ppb).
Choose the type of calibration required:
•ZERO
•SLOPE
• ZERO + SLOPE
At the end of the calibration, the results will be displayed (see
example in Historic on page 54).
