6.2.8.
“Zero” menu item
This is a zero concentration setting.
If you select
“Yes”
, a zero calibration is
performed.
If
“No”
is selected, the calibration value
remains unchanged.
6.2.9.
“Concentration” menu item
Allows calibration using an arbitrary
concentration value. The value of the last
calibration concentration value is saved
(it is not necessary to enter the value for
the same cylinder each time).
Where:
Кт
– current concentration value
Uт –
the current value of the signal on the ADC. It is convenient to use during calibration
to determine the end of calibration.
К
- set value of the new concentration.
To enter the calibration concentration value, the number of decimal places is determined
by the measurement range and does not change manually.
The concentration input is carried out exclusively by the buttons of the selection buttons
«Up»
and
«Down»
When pressed once, the least significant digit changes by one in the corresponding
direction.
When holding the button, the least significant bit begins to change on its own.
Further holding the button accelerates changes and moves to the next digit.
The value increases to the upper value of the measuring range and so on in a circle.
When you release the button at the right time, we get the right number. If necessary, it
can easily be edited with a single click.
