12.1.2 Graphical display
The digital recorder continuously records measured values
and depicts them graphically with respect to time (vertical
axis) on the display. In the graphical display the cursor (+)
moves from the top to the bottom. The measured value is
also displayed numerically (here, e.g. 6.410 pH) at the same
time.
If the digital recorder is started, you are moved first to the
Recorder
input window to define the details of the graphical
display.
l
Center
(1) determines the center of the measured value
range (here 7.000).
l
Delta
(2) determines the extension of the measured value
range starting from the center (here
Center
±
Delta
gives
a range of pH 0.000 to 14.000).
l
Timebase
(3) defines the length of the time intervals (5, 6)
shown on the display; the duration is also displayed on
the recorder strip (8)
l
Digits
(4) determines the number of the digits after the
decimal point
When the first period has expired, the recording of the
current period is displayed in the lower half (6) and the
previous period is displayed in the upper half (5).
