On the front of this instrument you will find two red lights marked with the maximum oil pressure
and temperature information. If there are any additional red or yellow lights on this instrument, the
operating range of these lights can be found on a sticker located on the side of the instrument (see the
AML at the back of this manual to decode this information). This instrument designates any "Caution
Range" with yellow LEDs, any "Maximum and Minimum Limits" with Red LEDs and the "Safe
Operating Range" with green LEDs. The "Safe Operating Range" on this instrument is equivalent to
the green "Normal Operating Range" and any unmarked areas on a analog gauge.
It is possible for any instrument to fail thereby displaying inaccurate high, low or jumpy oil
pressure or temperature 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 oil pressure or temperature
instrument failure. If you do not have this knowledge, contact the FAA or a local flight instructor for
training.

The OPT-1 is a precision oil pressure/temperature instrument featuring dual 90 degree analog displays.
These two displays provide the primary monitoring of oil pressure and temperature and have many advantages over conventional analog gauges as described below.
The digital display provides a method of monitoring oil pressure to 1 PSI or oil temperature to 1’F.
This can be very helpful in detecting trends and allowing you to control your aircraft to divert engine
problems.
The OPT-1 features long term accuracy and reliability. Since the OPT-1 does not incorporate any
moving parts (needles, bearings, springs, etc.) there is little to go wrong or wear out. Also, the internal
microprocessor assures accuracy and repeatability.
The OPT-1 incorporates an external oil pressure transducer mounted in the engine compartment. This
keeps the oil lines out of the cabin, reducing weight and assuring safety.
Analog Display:Analog Display:
Analog Display:
Analog Display:Analog Display:
The dual 90 degree analog displays provide a quick reference for oil temperature and pressure with
respect to their operating ranges. At a glance you can get a relative idea of where in the range you are
operating the engine and how close to the maximum limits you are. Precise information is provided in the
digital display.
An advantage of the analog display is its ability to emit a green, yellow or red light. With a quick
glance you can determine if you’re operating in a normal, caution or restricted range. Also, when you
exceed a maximum limit a red light will blink 20 times at full intensity to catch your attention and warn you
that a maximum limit has been violated. After 20 blinks the red light will stop blinking and display continuous red so it does not distract you.
During night operation the analog lights may be too bright. If so, turn the panel light rheostat up and
the analog lights will dim. The red (maximum limit) light will always be displayed at full intensity.
Digital Display (Oil Pressure):Digital Display (Oil Pressure):
Digital Display (Oil Pressure):
Digital Display (Oil Pressure):Digital Display (Oil Pressure):
By setting the toggle switch on the front of the instrument to "Press" you can monitor oil pressure
changes to 1 PSI. This can be very helpful in detecting problems or in monitoring trends. Abnormally low
oil pressure can be caused by an oil leak, low oil level, worn or defective oil pump, excessively high oil
temperature, contaminated oil or possible other problems. Abnormally high oil pressure can be caused by
a restricted oil line or cold oil temperatures. Oil lubricates and carries heat away from the bearing surfaces
in the engine. Without it, your engine will only run for a few minutes. Become familiar with your normal
operating oil pressure.
3
Rev: A 6/17/92
Oil pressure readings at or below 5 PSI will be displayed as "00".
If the digital display backlight has been permanently powered up (as recommended), the digital
display will be easier to see during low ambient light conditions and at night.
Digital Display (Oil TDigital Display (Oil T

Digital Display (Oil TDigital Display (Oil T
As the oil passes through the engine, it is heated. It then passes through the oil cooler and reaches a
stable temperature depending on internal engine temperatures, oil flow (pressure, etc.) and oil cooler
efficiency (airspeed, etc.). A change in any of these parameters will cause the oil temperature to increase
or decrease. With the 1’F resolution of the OPT-1, oil temperature changes can be detected easily. This
allows the pilot to diagnose many problems that may never be noticed with a less sensitive gauge.
Maintaining your oil temperatures within operating limits is essential. If the oil exceeds its maximum
operating temperature or if it is operated at excessively high temperatures for a long period of time, the oil
will break down and it will not possess the necessary lubricating properties to protect your engine. The
formula for long engine life is to change your oil at regular intervals and watch your oil temperatures.

Replace your existing primary oil temperature probe with the probe provided in the kit. Oil temperature can vary throughout an engine. Your engine’s oil temperature specifications are based on a specific
location of the oil temperature probe. If this instrument is to be used as a primary instrument, the oil
temperature probe must be installed at the primary oil temperature pick up point. Otherwise the OPT-1
must be placard as a secondary instrument.
If the oil temperature probe must be removed on a regular basis to drain the oil, order a precision
connector for the probe and extension cable to allow for easy disconnect.

Be sure the connectors mate properly. If the tab in the male connector gets bent, it can wedge itself
between the red nylon and metal female receptacle. This can result in an intermittent connection after
about a month or more. If the connectors are removed several times the female connector can become
loose. If this happens use a pair of needle nose pliers and tighten the metal receptacle inside the female
connector.

In the wire harness is a 3 foot red and black wire used for instrument power and ground and a 6 foot
red and black wire used for the pressure transducer. Route the four 6 foot pressure transducer wires (red,
black, green and white) in the wire harness to the pressure transducer and cut to length. These wires
maybe spliced if extra wire length is required. Install the male connectors supplied with the kit on the four
wires and connect them to the pressure transducer matching the colors of the wires. Be sure the wires are
doubled over and double crimped onto the connectors.

Check Instrument Operation:Check Instrument Operation:
Check Instrument Operation:
Check Instrument Operation:Check Instrument Operation:
Check instrument operation as follows:
1. Turn the master switch on (engine off) and verify that the instrument sequences through all the
analog lights. A problem at this step could be caused by poor connections on the red and/or black
leads.

Rev: A 6/17/92
2. Set the instrument toggle switch to "Oil Press" and check for a digital oil pressure reading of "00."
A problem at this step could be caused by a poor connection or crossed pressure transducer wires.
The voltage on the pressure transducer wires (with the transducer connected to the unit) should mea-
sure as follows:
Red Wire - +5 Volts.
Black Wire - 0 Volts.
Green Wire - 1.65 Volts.
White Wire - 1.65 Volts.
3. Set the instrument toggle switch to "Temp" and check the instrument to read proper oil temperature.
A problem at this step could be caused by poor or improper connections between the oil temp probe
and instrument. If the instrument is not connected to the oil temperature probe it will read cabin
temperature. By applying a small amount of heat to the oil temperature probe the oil temperature
readings will increase one degree at a time.
4. Check the digital display backlight. With high or medium ambient light it is hard to see the digital
display backlight (it is only required during low ambient light conditions but should be on all the
time).
5. If the analog LED dimming wire has been connected, turn the panel light rheostat up and look for
the analog lights to dim.
Note: If any red warning light is on, none of the analog lights will dim.
6. Start the aircraft engine and check the digital and analog displays to read oil pressure properly. A
problem at this step could be caused by a poor connection or crossed pressure transducer wires.
Measure the voltage on the pressure transducer wires as listed in step 2. If the voltage measurements
are correct and the oil pressure reads "00", the white and green wires between the pressure transducer
and instrument may be reversed.
7. With the engine running, check the digital and analog displays to read oil temperature properly. If
there is a problem at this point see step 3 above for troubleshooting information.
