Electronics International OPT-1 - Manual (Page 6)

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.

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.
