Important Installation Information
All steps must be read before installing a probe.
F
1. Leave slack in the cable to allow
for engine movement and vibration.
S.S. Washer.
2. Do Not Overtighten.
Over time, tight wire
wraps will cause the wire
to break.
Hose Clamp.

E
Male Conn.
3. Both clip rings must be on
the inside of the hose clamp.
The rubber band is used to hold
the washer on during shipping.
4. The tab inside the male connector must be centered (not
bent up or down) to mate properly. Check each connector
before installation. Two drops of oil on the connector will
protect it from corrosion for many years.
5. If you remove a connector, double over the wire
before installing it into a new connector. Each connector must be double crimped very tightly.
6. If connectors have been disconnected several times the female connector may become
loose. If this happens use a pair of needle nose pliers to retighten the female recep-
tacle then mate the connectors.

AD's and/or STC's may set forth additional limitations on the operation of your engine.
owner's and/or installer's responsibility to determine proper instrument calibration and range markings
for your aircraft.
It is possible for any instrument to fail thereby displaying inaccurate high, low or jumpy readings.
Therefore, you must be able to recognize an instrument failure and you must be proficient in operating your
aircraft safely in spite of an instrument failure. If you do not have this knowledge, contact the FAA or a
local flight instructor for training.
The ability for this product to detect a problem is directly related to the pilots ability to program proper
limits and the pilots interpretation and observation skills.
The pilot must understand the operation of this product before flying the aircraft. Do not allow anyone
to operate the aircraft that does not know the operation of this product. Keep the Operating Manual in the
aircraft at all times.

OPERATING INSTRUCTIONS
Features
1. Instruments:
The Electronics International line of primary TIT/CHT instruments offer the following features:
A. Digital Display - The digital display allows you to read absolute temperatures at a glance. It does
not require interpretation of dials or tic marks. In a short period of time you will be come familiar with
the normal operating temperatures of your engine. Abnormal temperatures will be easy to spot. The
digital display is easily viewable in direct sunlight. If the instrument backlight has been permanently
powered up (as recommended), the digital display will be easier to see during low ambient light conditions and at night.
B. Over Temperature Warning Light - Over the digital display is a warning light that will turn on any
time the temperature exceeds the maximum operating temperature limit indicated on the front of the
instrument. Also, there is a control line that may be use to turn on Electronics International's AL-1
remote mounted warning light. During power-up the warning lights will flash. This indicates the light
and over-temp circuitry is operating properly.
C. 1 Degree Resolution - The digital display resolves temperatures to 1 degree. This allows you to
interpret trends quickly. This can be very helpful in diagnosing problems and leaning your engine.
Also, any unit may be ordered to display in degrees F or degrees C.
D. 1/2% Accuracy - Electronics International Instruments are not affected by shake, shock, vibration,
tilt, stick-slip, bearing wear, spring wear, lead resistance, probe resistance, magnetic fields or the many
other factors that plague analog instrument accuracy. All E.I. instruments are temperature compensated
to read cabin temperature when a probe is disconnected. E.I. instruments should never need
recalibration.
E. Flexibility - Electronics International instruments are compatible with any type K ungrounded
probe. Lead resistance does not affect the accuracy of these instruments. You may use any length
extension cable between the unit and the probe without affecting the accuracy of the instrument.
F. Upgradeable - Any single channel TIT and/or CHT unit may be upgraded to a full multi-channel
analyzer by simply adding a Primay Remote Switch to the system. The instruments, remote switches,
extension cables and probes were designed in a modular fashion with slip-on connectors. This means a
remote switch may be added to your existing system by simply mounting it into your instrument panel,
installing the additional wires and probes and plugging it in. You do not have to buy a new system to
upgrade to a full analyzer.

2. Primary Remote Switches:
A. Used with a Primary TIT Instrument - A Priamry Remote Switch may be connected to a TIT
channel on any appropriate Electronics International Instrument. This gives the TIT instrument
multi-channel EGT capability. Only the TIT or any EGT cylinder may be displayed on a Primary
TIT instrument. The channel marked "Primary" on the remote switch is used to display TIT.
B. Used with a Primary CHT Instrument - A Primary Remote Switch may be connected to a CHT
channel on any approprate Electronics International Instrument. This gives the CHT instrument
multi-channel CHT capability. Only CHT's may be displayed on a Primary CHT Instrument. The
channel marked "Primary" on the remote switch is used to display the primary CHT cylinder (i.e., if
cylinder number 3 is the primary CHT cylinder for your engine, cylinder 3 will be displayed on the
CHT instrument when the remote switch is set to the channel marked "3" or the channel marked
"Primary").

Note:
during flight.
When using a Primary Remote Switch, the switch must be left in the "Primary" posistion
TIT
1. Maximum Operation TIT Limit (Red Line):
Do not operate your engine above the Maximum Operating Temperature Limit as indicated on the front
of this instrument. Operating above TIT Red Line can cause turbine housing and component failures,
detonation or preignition (which will destroy engine and turbine components), loss of engine power,
reduced turbocharger and engine life and can cause a fire hazard. It is essential to operate your engine
within its TIT operating limits. Electronics Internationals TIT instruments give you three mechanisms
to detect an over-temperature limit (Red Line) condition.
A. The Large Digital Display gives you a fast and very accurate indication of your current temperature condition. This instrument will display temperatures from ambient to 1999F in 1F
increments. This also allows you to interpret rate and trend information at a glance.
B. This instrument incorporates an Over-Temperature Warning Light. This light will come on any
time the TIT is above the Maximum Operating Temperature Limit as indicated on the front of this
insturment. This light provides the advantage of catching your attention without your having to
scan or interpret the display.
C. This insturment also comes with an External Warning Control Line. This line can be connected
to an external light in a control panel or mounted in front of the pilot. This control line will turn on
the external light any time the TIT exceeds the Maximum Operating Temperature Limit as indicated
on the front of this instrument.
