EGT-100 Operations & Installation Manual – Ver. 1.9 – June 5, 2003
If the instrument is left in the intensity mode without any changes for more
than eight seconds it will revert to the last selection. We recommend the use
of the internal intensity control for the most accurate control of the brightness
of the instrument.
AUTOMATIC MODE
Moving the
A M S
switch to the
A
position will place the instrument in the
automatic mode.
In this mode it will select and display the temperature for the hottest cylinder.
All cylinders are scanned in less than one second and the display updated at
the same rate.
This mode of operation is the single most important feature of this
instrument and should be used during leaning and normal operations.
Leaning in the automatic mode ensures that no cylinder is overheated during
the process.
If the instrument is switched from the automatic mode back to the manual
mode it will revert to the last selected manual function.
For complete leaning instructions and limits refer to your engine
manufacturers recommended procedures, then select the AUTO mode for a
hassle free leaning process.
DISPLAY
The bar display will display a graphic representation of the selected cylinder
temperature between the defined low and high limits. Each bar represents
1/10 of the temperature range between the low and high limits.
For temperatures in excess of the high limit the two upper bars (red bars) will
blink. Once the temperature cools and is within the limits the blinking will
cease. The over temperature blinking does not occur in the STEP mode.
Temperatures below the low limit will only be displayed on the four digit
display.
If the temperature is below 200ºF the display will read
COLd
. As soon as the
temperature exceeds this limit it will be displayed.
