8. View or Adjust the 0% & 100% Thermal Signal Scaled Bar Graph View
There are two views of the Signal Data available for display on the
Thermal Signal Bar Graph.
1.
The
Baseline Bar Graph View
shows the maximum possible span/complete thermal range that the
CLASSIC 800 is capable of measuring.
2.
The
Scaled Bar Graph View
focuses only on the portion of the total thermal range required for each
application (oil, water, gases). Once the 0% Thermal Signal and 100% Thermal Signal settings are defined,
this range
(Scaled Bar Graph View)
will be displayed as 0% to 100% on the Thermal Signal Bar Graph
at all times. The
Scaled Bar Graph View
can only be displayed by pressing and holding the
Left Arrow
while in
Run Mode
. When the zero (0%) and 100% LEDs illuminated, the switch is set for the widest range
possible.
To illustrate this principle refer to Figure 22.
The LED-0 pointer is shown set to 50% of Baseline and the LED-100 pointer is shown set to 75% of Baseline.
The result is that the Scaled View appears to zoom in on the area of the Baseline data that is framed by the LED-
0 and LED-100 Pointers.
The data, indicated by the single illuminated LED, is at 55% of Baseline but on the Scaled View it is shown as
20%. This is because the data is at only 20% of the values framed by LED-0 and LED-100.
