C) pH scale range and screen graph.
•
The
pH range,
extended range is b 7000 and - 7000 mpH. To select the range
pH scale use arrows
<UP>
and
<DOWN>
or the mouse to set the number.
•
The base-line is normally between 0
±
100 mpH. The selected pH range, for centred base-
line, always remains the same (also when the user leaves the program), until the user
changes it.
•
In the
screen graph
the measure time (sec.) is on the x-axis; the pH scale is on y-axis (in
this case minimum pH is -560 mpH and maximum is not visualised because under the
File
window).
•
During alkaline reactions (OH
-
), which increases the pH value, the baseline on the screen
goes to higher values. During reactions which release hydrogen ions (H
+
, acidification) the
baseline on the screen goes to lower values.
D) Temperature Actual measurement temperature is shown only after the start of measuring
cycle (after
GO
command or F5 function key), until then it is displayed the temperature value
corresponding to the last measurement made.
E) F) Parameter name It is a "non editable section" from this window (see method editing
option at § 4.2.3); the name of the method described in the picture is COMBITEST giving
three parameters ( pH, total acidity, g fructose).
