To compare the results of two different parameters, it is possibly
more significant to display the results of both parameters as a
24 h-Average.
To display as a 24h Average:
1. Activate the graph whose data must be displayed as a 24h
average.
2. Press Options and then press 24h Average to display a graph
that shows the results as a 24 hour average. The time range is
from 0:00 h–23:59 h.
Note: To display the second graph as a 24h Average, press the
black/orange box. Press Options and then press 24h Average.
It is possible to adjust control limits for every parameter to identify
discrepancies from the usual process, interferences and exceeding
limits. To adjust the control limits:
1. Press Control Limits to adjust the control limits of the active
graph.
Note: Press the black or orange box to switch between the graphs.
Note: The colors of the displays vary, due to the selected color
palettes in the Select Color menu.
2. Select On in the Control Limits menu.
3. Press the field below Upper Control Limit or Lower Control
Limit to enter a new number.
Note: Use the alphanumeric keypad to enter the number and press
OK to confirm.
Readings outside the control limits are displayed in red.
Note: The Control Limits are displayed as a line only for the active graph.
Note: When Control Limits are entered for both graphs and the graphs are
displayed as dots or cruxes, all readings outside the limits are displayed in
red.
