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 condi-
tions 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.
