The Bar Graph Display allows visual comparison of EGTs and CHTs at a glance. It also allows you to see where
the EGTs and CHTs are operating in their normal operating range (i.e., high EGTs will be displayed with many
bars lit in a column and low EGTs will be displayed with few bars lit in a column).

The scaling and range of the EGT columns of bars may be customized to accommodate any engine or pilot’s
preference (see the “Programming the Range of the EGT Columns of Bars” section of this manual).

Step Switch:

When operating in the Normal or Normalized Operating Mode, each time the Step Switch is pushed to the right
the UBG will advance the digital display to show the next temperature or function. Each time the Step Switch is
pushed to the left the digital display will show the previous temperature or function.

Each time the Step Switch is pushed to the right, the UBG indicates the following temperatures or functions in the
digital display:

1. Displaying the EGTs and CHTs:

The EGTs and CHTs will be indicated in the digital display, beginning
with cylinder #1. The left side of the digital display will indicate
exhaust gas temperatures and the right side of the digital display will
indicate cylinder head temperatures. The lit box around a specific
cylinder number (located at the top of the columns) coincides with
which cylinder is being digitally displayed. Each time the Step Switch
is pushed to the right the next cylinder will be displayed.

2. Displaying a Temperature on the 7th Column of Bars:

If installed in a 4 or 6-cylinder engine, after the last EGT channel has been displayed on the UBG, push the
Step Switch once to the right to digitally display the temperature on the 7th column of bars (if the 7th
column is activated). The 7th column of bars may be used to display
EGT and CHT (on a 7-cylinder engine), or TIT or Oil Temperature (on
a 4 or 6-cylinder engine), or it may be turned OFF. Installation and
programming of the UBG will determine what, if any, function will be
displayed on column 7.

The scaling and range of the 7th column of bars may be customized
(independent of the EGT columns) to accommodate any engine or
pilot’s preference (see “Programming the Range of the 7th Column of
Bars”).
