The UBG-16 was designed for use in a single engine aircraft. (For twin engines, use two UBG16’s.)
On the back of the UBG-16 are three circular connectors. As seen in
the diagram to the right:
The first 1 to 7 channels of the LEFT 16-pin connector are used to
monitor EGT’s. Any remaining channels may be used to monitor
other functions.
The first 1 to 7 channels of the RIGHT 16-pin connector are used
to monitor CHT’s. Any remaining channels may be used to
monitor other functions.
The small 9-pin connector connects the instrument to power,
ground, display intensity control, RS232 Recorder and any warning devices.

The UBG-16 comes with three preassembled wire harnesses which simply plug into the three
circular connectors at the back of the instrument. Two of the wire harnesses are identical. One
will be used to connect the EGT probes to the UBG-16 and the other will be use to connect the
CHT probes to the UBG-16. The wire harnesses were assembled with only enough cables to
accommodate the EGT and CHT channels. Any additional temperature measurement (TIT, OAT,
Carb Temp, Cowl, etc.) requires a Type K thermocouple extension cable be added to the appropriate harness. Any desired function such as RPM, M.P., Oil Pressure, Fuel Pressure, Fuel Flow,
Gyro Vacuum, Volts, Amps, etc., requires an Electronics International Functional Module be
added to the appropriate harness.
The UBG-16 does not require any programming before installation. All setup can be accomplished
on the face of the instrument. The UBG-16 does not use any internal batteries, so once installed
the instrument never has to be removed from the panel.

Look at each exhaust stack and determine the best location at which all of the EGT probes can be
mounted at the same distance down from the exhaust ports. The ideal location is 1 1/2", but ease
of installation should prevail. Drill a 13/64" diameter hole in each exhaust stack. Insert the probe
and tighten the hose clamp. As the hose clamp is heated and cooled, it will become loose as it
conforms to the exhaust stack. After the first 10 hours of operation, each hose clamp should be
retightened.

There are two identical pre-wired Extension Cable Harnesses in the installation kit. One end of
each harness has a 16-pin Circular Connector and the other end has red Slip-on connectors on the
individual extension cables (see the Wiring Diagram at the back of this manual). There is a type K
thermocouple extension cable for each EGT and CHT temperature to be measured. The end of
each extension cable in the harness has a piece of yellow heat shrink marked with its channel
number. One of these harnesses is to be connected to the EGT probes (and LEFT connector on the
UBG-16) and the other is to be connected to the CHT probes (and the RIGHT connector on the
UBG-16). Refer to step 4 (Configuration Form) to identify which harness will be used for EGT's
and which will be used for CHT's.
Mark the Circular Connector that will be connected to the EGT probes. The first 4 or 6 channels
(starting with channel #1) are used to monitor EGT's. Any additional channels may be used to
monitor other temperatures or functions. There are 8 channels available on each 16-pin Circular
Connector. Any channel used to measure a temperature other than EGT or CHT (TIT, OAT,
Carb Temp, etc.) will have a type K thermocouple extension cable lose in the kit. Plug any additional extension cables into the appropriate pins of the Circular Connector (see "Appendix A" at
the back of this manual).
Any channel used to monitor functions other than temperature (RPM, M.P., Oil Pressure, Volts,
Amps, etc.) will require a Functional Module. Installation of a Functional Module will be covered
later in this manual.
Mark each of the Type K thermocouple extension cables in this harness (on the yellow heat shrink)

circular connector about 9 inches back from the panel. Tie wrap the harness in place approximately 1 foot back from the circular connector. This will allow the harness to be flexible and
accommodate varying lengths in instrument wires.

If a channel on the UBG-16 is to be used to monitor a function other than temperature, an appropriate Functional Module must be installed. A Functional Module is a small box with circuitry
used to convert pressure, RPM, Voltage, Amps, etc. to an appropriate signal the UBG can display.
This signal can be connected to any unused channel on the UBG-16. These modules are small and
light and are tie wrapped under the instrument panel. They come with a Circular Connector so
they may be installed and removed easily. Below is a list of the functional modules available:
FM-OP - Oil Pressure FM-FP - Fuel Pressure
FM-MP - Manifold Pressure FM-Gyro - Gyro Vacuum
FM-RPM - RPM FM-VA - Volts/Amps
FM-Flow - Fuel Flow (Flow only)
You may install any Functional Modules at any time. Installation Instructions for the various
Functional Modules are included with the modules.
The UBG-16 has optional items that may be installed. These items are listed below.
MUX-8A - Data Recorder AV-17 - Voice Annunciator
AP-7V - Vertical Annunciator Panel AP-7H - Horizontal Annunicator Panel
ATG-1 - Annunciator Tone Generator CP-1 - LED Intensity Control Pot

A. Turn the master switch on and look for a near ambient temperature reading on each tempera-
ture channel. If the instrument does not power-up (display a reading), check the power and
ground leads (red and black leads) for an open, loose or poor connection.
If you suspect that any channel is not receiving a signal, remove the probe from the engine
(leaving it connected to the Extension Cable) and apply a temperature to it. Look for an increase in reading on the display for that channel. Check the other channels for an increase in
reading. You may have connected the probe to the wrong Extension Cable. If the reading is
decreasing, you may have reversed the connectors on the Extension Cable leads (the yellow
wire on the probe must connect to the yellow wire on the Extension Cable).
B. Start the engine and check each channel for a proper reading. On the ground (after a few
minutes) EGT’s will read around 900°F and CHT’s will read around 200°F. If you suspect any
channel is not receiving a signal properly, see step A of the “Troubleshooting” section of this
manual.

Because high reliability is designed into Electronics International’s equipment, there is no reason to put
up with poor operation. We have few problems with our probes, cables and units and installation is

If you have more than one problem,
them at once can be confusing and misleading. In many cases fixing one problem first will lead you
to the solution for fixing all of the problems. Therefore, take one problem on one channel and
proceed with the following:

If there is an identical symptom on each channel, then the instrument may have a problem. But if
even one channel of the instrument is operating properly, the instrument probably does not have a
problem. A good method to test the instrument is to remove all the Extension Cables by disconnecting the Extension Cable Circular Connector. Then look for a reading on all channels to be
near cabin temperature for temperature channels or zero for channels measuring functions other
than temperature (RPM, Oil Pressure, etc.). The only inputs the UBG requires to operate properly and measure cabin temperature is power (red lead) and ground (black lead). Check the
power and ground leads for proper connection (pull on the wire at each connector).

There are two good methods of testing a probe. Perform one or both of the following:
1.1.
1. A probe can be tested with an ohmmeter. Disconnect the probe from the Extension Cable.
1.1.
When testing the resistance between the connectors, the probe should measure a “short” (less
than 5 ohms). When measuring from one lead (either lead) of the probe to the probe sheath
(metal tip), there should be an “open” (10k or greater).
2.2.
2. Another method of checking a probe is to plug the suspected bad probe into a channel that is
