EG T-701 Rev B
The EGT-70 I temperature ind icator displays temperature dig itally and in analog format. The EGT
as d isplayed is based on probes located near the exhaust outlet for each cylinder and the TIT
probe, if installed, is adjacent to the turbo charger. These probes are not necessarily collocated
1
he primary probes therefore, EGT-701 may not indicate the same as the aircraft primary
in~.. ments. The analog d isplay is an electronic bar graph (vertical columns, one per cylinder) of
EGT
&
T IT temperatures presented as a percentage of
I
650°F. Below the vertical columns the
specific value for EGT and CHT are displayed digitally. The dot over the column indicates which
cylinder's d igital info rmation is presently displayed. The missing bars at the base of the columns
ind icates the hottest and coldest Cylinder Head temperature trend . During Lean Find mode the
leanest cylinder is d isplayed along w ith the fue l fl ow (optional) at that time. Depressing the LF
and STEP button simultaneously brings up the adjustable scan rate fu nction, OAT in °C or 0 f .
Depress the LF butto n will change the value of the rate or OAT in °C or 0 f . Exit by Depressing
STEP.
If the EGT-70 I buttons arc not depressed fo r IO minutes the system will start scan ni ng
auto matically. Depressing the STEP button wi ll stop the automatic scan and index throug h all the
fun ctions available. During constant power cru ise, if the the LF button is depressed for fi ve
seconds the bargraph will level at mid scale. The leveled bars represent the peaks of each column.
Each bar represents IO °F and now acts as an EGT & TIT trend monitor, quickly showing an
increase or decrease in temperature. Depress again to return to normal; nothing else is affected.
With the fuel flo w o ption there is a three position toggle switch. T he positions are: I ) EGT ,
di o;l\l and bargraph display of temperatures, 2) FF, digital display ofGPH, REM and USED
F ) Temperature barg raph remains. 3) Bot h, cycles throug h everything installed. The data port
output, sends RS232 serial data every 6-sec.
Options of Fuel Flow, TIT, OAT, IAT (induction air temp.), OIL, BAT (vo ltage) and are only
di splayed digitally with head lines after the number, as "230 OIL" or " 14 GPH" . A large value (50
+) of "C LO" indicates shock cooling usually associated w ith rapid descents at low power.
Optional functions not installed will not d isp lay.
RPM
is displayed constantly in the upper
display with no alarms. MAP is shown in the scan display.
