Controlling the G2 instrument: The instrument has two control knobs that operate
combination rotary and push button switches. The top knob in general controls
screen selection while the bottom knob controls items within the given screen.
Each screen assigns its own functional needs to the controls that may change
depending on context. A screen may also label the controls with guidance information
like “Push to exit”.
The Bar-Graph Display Screen: The Exhaust Gas Temperature is displayed in white bar graph
form and is interpreted much like a conventional mercury thermometer. The
higher the bar, the higher the temperature.
The cylinder head temperature is displayed in green single
bar format. During normal operation it shows as a green illuminated bar in the
lower half of the bar column. Since EGT is normally higher than CHT, the green
bar which represents CHT is on top of the white illuminated EGT bar and stands
out clearly. However, when the engine is shutdown, the EGT quickly drops to
zero and the cylinders remain warm for sometime.
The G2 provides a reliable indication of cylinder head
temperature even with the engine shut down. Should an EGT probe fail, the
entire EGT column for that cylinder will go blank, and the numeric indication
will show --- that is dashes, but the CHT bar will still remain green. The
failure of one probe will not affect the display of any other probe.
An Easy Upgrade: A key requirement of the G2 design was compatibility with
previous GEM’s. We strive to never leave our loyal customers behind. Packing
all the functionality of the G2 in package half the size of the original GEM
took us to the limit of our patience many times but it was worth it.
Fortunately its amazingly compact circuits will be built by robotic machines
because most of the parts are too small to handle and too difficult to be seen
by eye. Products like the modern cell phone have driven the electronic assembly
technology we use a long way.For faster processing, print the order form and complete it. Scan it to your computer and upload it during the check out process or email it to EMAPAsales@gmail.com Order Form
