GEM SERIES 602 Graphic Engine Monitor
Aspirated 4 or 6 Cylinder.
The GEM 602 is designed for use
with all 4 or 6 cylinder piston engine aircraft. The instrument
graphically displays up to 12 critical engine temperatures in
a single instrument in an easy-to-read bar- graph format on a
brilliant plasma display.
The GEM 602 features include:
- Displays up to 12 EGT, CHT temperatures.
- Lean Mode: is used during cruise
to identify the leanest cylinder. Lean Mode can be entered at
any time. The GEM's microprocessor analyzes EGT temperatures
and indicates the leanest cylinder by blinking the appropriate
- Monitor Mode: each time that
Monitor Mode is entered, the GEM microprocessor stores the EGT
values into memory. Should any cylinder's EGT subsequently rise
50°F or more, the corresponding column will begin blinking
to signal change in fuel flow or ignition.· Test Mode:
is designed into the GEM system should trouble be suspected.
Entering the test Mode causes each bar column to stack up, a
bar at a time, until fully illuminated, then blank. Each successive
column until all six have be done.
- Automatic selection of the correct
number of cylinders.
- Automatic intensity control
for all lighting conditions.
- Whether you fly a home-built,
war bird, or latest model aircraft, the GEM 602 provides a complete
picture of EGT and CHT at a glance.
