OCTANE NUMBER METER
FOR MOTOR GASOLINES
USER INFORMATION
The meter is easy to use, and you will easily see it for yourself.
The unique feature of the meter is that you may check  octane number in the moment of filling fuel at the gas station.
After filling 2 - 5 liters in the tank through the metering pipe of the meter, you may decide if you should fill more or not if, when buying AI-95, your meter shows that its octane number is, for example, 88,0. Most probably, this gas station is selling fuel with octane number artificially increased with octane-increasing additives. Practice shows that acceptable deviation of octane number is within ±1.5 units of the number claimed by the gas station.
In case you always buy gasoline at the same gas station, periodically checking your fuel helps you be sure that its quality remains the same, or reveal a sudden change of gas characteristics.
1. PURPOSE
OKTIS-2 is intended for the determination of motor gasoline octane number in Russian gasoline standards AI-80, AI-92, AI-95 and AI-98. Principle of meter operation is based on the dependence between dielectric permeability of gasoline and its research octane number (RON).
The meter can operate in 2 modes: in continuous-flow mode while filling car tank at the gas station and in sensor immersion mode.
The meter is used as an indicator permitting the car owner to obtain information on the main parameter of gasoline quality.

4.  SAFETY MEASURES
Use the meter in the open air or in a well ventilated room preventing gasoline vapor concentration.
When working with the meter, IT IS FORBIDDEN TO:
•   supply power to the meter from any outside source.
•   change batteries when the meter is in contact with gasoline;
•   use the meter near a source of open fire.
After the use, please shake the meter several times to shake off drops of gasoline from sensor surface in measuring tube and replace the meter in its case.
Never use acetone or other solvents for washing the metering tube.
5. DESIGN AND PRINCIPLE OF OPERATION.
The meter is designed as a one-piece device (see fig.1) comprising three main units. The body includes compartment 1 containing electrical parts and transition compartment 2 with seal rings. Metering tube 2 with sensor 3 are secured in the transition compartment. Transition compartment 2 and metering tube 3 form a channel either containing or passing through a flow of gas, and compartment 1 contains electronic unit with numeric display 4 and
batteries.

8. TROUBLESHOOTING.
If, after the meter is switched on, ticker bar instead of '00' displays a stationary three-element message, it means that meter sensor in tube 3 is not fit for work (metal chips, dust, drops of water, or other foreign matter). In this case, wash the sensor in metering tube 3 in gasoline, shake off the remaining drops, purge with air, and dry. For the complete removal of contamination after washing, you may use paper strips.  Sensor may be washed in rectified rubber solvent gasoline (NEFRAS-S2-200 TU38.401-67-108-92) KALOSHA by repeated dipping of the tube in a vessel containing gasoline; gasoline level in the vessel should be above mark 7. After '00' appears in the display, the meter is ready for work.
9. STORAGE AND TRANSPORTATION
The meter shall be stored and transported in factory case with closed cover.
No dust, acid and alkali vapors, aggressive gases or other corrosive impurities should be present in meter storage places.
The meter may be transported by any mode of transport.
When the meter is not used for a long time (over 2 months), please
remove batteries.
Do not leave the meter in direct sunlight for more than 1 hour.
10. WARRANTY LIABILITY AND
WARRANTY MAINTENANCE RULES
Manufacturer guarantees replacement of a meter which gets out of order within 24 months after the meter was sold, provided the meter was operated in compliance with this User manual. When buying the meter, ask the salesperson to fill Section 11 (Sale Registration). If this section is not filled or filled incorrectly, no claim for meter quality is accepted and no warranty
repair is made.

When gasoline reaches sensor in tube 3, sensor parameters are changing; microprocessor compares them with data stored in memory, and digital display 4 shows figures corresponding to gasoline octane number. Meter is switched ON by pressing button 5 once, until it locks. Repeated pressure on the button switches the meter off.
Microprocessor program supports basic mode, expanded mode, reading correction for gas temperature mode and reading correction for sensor contamination mode.

PREPARING FOR OPERATION
• Push button 5 ON/OFF in OFF position.
• Remove cover 6.
• Observing the polarity, install two batteries (type
АА
).
• Set the cover in place and fasten it with screws.
• Press button 5 at compartment 1 until it locks.
A ticker bar will appear in the middle of the digital display 4, and in a few moments figures ‘00’ will be displayed. The meter is ready for work.
“РАЗ” (RAZ) message on the digital display indicates that batteries are discharged. They should be replaced.
7. METER OPERATION.
The meter may work in two main modes:
•
continuous
-flow mode
with gasoline flowing along
metering tube 3;
•  sensor
immersion mode
with metering tube immersion in vessel with
gasoline.
For operation in
continuous
-flow mode,
install the gas station fuel gun as far as it would go into transition compartment 2 through rubber seals. Install metering pipe 3 in fuel tank filler, press button 5 at compartment 1, achieve even flow of gas through tube 3 by fuel flow regulator on the fuel gun without actuating fuel gun shutoff valve. In a few moments ticker bar in the middle of display 4 will be replaced by figures indicating octane number of gasoline flowing through the meter. Ignore the first reading and wait for the next 2-3.  Then stop filling, switch off the meter, remove it from fuel gun and shake off the remaining fuel from the tube.
This mode allows the possibility of monitoring gasoline quality in course of filling. If there are air bubbles in flowing gas, meter readings will be too low.
For operation in
sensor immersion mode
, place metering pipe 3
vertically or aslant in a vessel filled with gasoline above the mark 7.

Press button 5 at compartment 1. Make sure there is a ticker bar in the middle of the display and take the readings. Ignore the first reading and wait for the next 2-3. Then switch off the meter, remove it from gasoline and shake off the remaining fuel from the meter.
In course of measurements, two-or three-digit octane number values are displayed with increment of one. To obtain more accurate information on measurement, you can press button 8 KOPP (CORR) (see p.10), and values with increment of 0.1 will be displayed.
Measurement cycles are repeated 10 times; then, the display dims, and an intermittent sound signal is heard, reminding you that you should switch the meter off.
Often gasoline contains dissolved foreign matter (in particular, (motor oil, fuel oil, diesel oil and other poorly evaporating substances), remaining after gasoline is evaporated, and accumulating at sensor plates.  Such contamination affects initial properties of the sensor and results in too high meter readings.
To eliminate this problem, the meter has measurement program correction mode, taking into account sensor contamination. To make a correction, press button 8 “CORR”, using a thin object; press button 5 to switch the meter on, and release button 8. After a double sound signal, lower part of the display will show:
•  two ticker bars,
• absolute value of sensor resistance deviation from factory setting in standard units,
•
ЗАП
(ZAP) message
Deviation will be stored in meter memory and will be factored in while displaying octane number value.
Deviation value “000” means that the sensor is clean.
Each subsequent correction eliminates the previous one. Only the last correction matters in measurement.
