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):

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.
