To initiate a Hold, press Hold from the Flue Gas menu. The
following screen is representative of a hold screen:
4.5.1.12 Z OOM
The Zoom function is used to change the displayed font size and
the number of lines capable of displaying on a single screen.
There are two fonts and therefore types of layout available:
• 10-line layout
The 10-lines layout is the default layout set at the factory.
Measured parameters are shown on the left whereas readings
and units are shown on the right.
•
5-line layout
This layout reduces the number of displayed lines and
increases the font size to facilitate the reading of the display
from a greater distance. In this layout, measured parameters
and units are on the left and readings only are on the right.
The zoom button toggles the screen display between the two
layouts as shown in the following screen displays.
Note: After the device is switched off and on again, the display
resets to the 10-lines layout automatically unless the 5-
lines layout was a measurement configuration activated by
a macro.
