Standard 2
In the "Standard 2" window, which only appears if the value can be modified, the
value of the Standard can be set using a number pad and will be used during the
second step of the calibration for the calculation of the GAIN.
The value which can be set cannot exceed the minimum and maximum values.
Site
If a NTU sensor or a MES sensor is connected to the device and when selecting
a calibration in mg/L or in g/L, the calibration process will be saved in a file saved
under the name of the site. Up to 10 sites can be configured, each identified
using 8 characters.
Pressing on the
icon validates the setting of the calibration data and starts the first calibration
step ("Standard 1" window).
In the window corresponding to the first step in the calibration, the first line indicates the value of the
N1 standard and the second line presents the measurement delivered by the sensor in contact with
the standard solution.
A message indicates if the value measured by the sensor is stable or not. The confirmation of the first
calibration step (gearwheel icon) initiates the second step ("Standard 2" window).
Once the second calibration step has been confirmed, a summary window appears which presents the
information about the values of the standards used and the coefficients calculated.
The appearance of the
icon on a coefficient calculation line indicates that the coefficient has
been confirmed, whereas the
icon indicates that the coefficient obtained is out-of-range.
The table below presents the calibration steps for each parameter:
