1 - WHAT A HALLMETER The Hallmeter monitor an air / fuel that works with Information This provided the lambda probe which in turn detects the oxygen content in the flue gas, and generates Information bulb icon This millivolt . So the Hallmeter that build a voltmeter with a range of 0.1 volts to 1.0 volts, represented by 10 LED (light emitting diode) going from the rich lean mixture. See the graph below.
2 - The Hallmeter applications can be used on any vehicle that requires special care as to the correctness of feeding, especially where common supercharged cars breaking engines due to lack of fuel, leaving work with the vehicle and causing a lean mixture on warming, rich mixture can also impair performance of the preparation but in so harmful as to lean. 3 - OPERATION OF PROBE
The Lambda sensor detects the concentration of oxygen in the exhaust gas, and informs the control unit about its presence with respect to the sampling air within the sensor estequiomtrico bulb icon calculation. The sensor generates millivolts as the content of oxygen in the exhaust gas. The lambda sensor element shaped thimble manufactured dioxide Zircnio (one cermico material) internal and externally covered by a thin layer of microporous platinum. This element actually bulb icon a galvnica clula (works like a battery) excited by temperature and oxidation of the material left in the combustion. High values of milivoltagem: mean that virtually all the oxygen injected into the combustion chamber was burned Values Basses milivoltagem: beyond the necessary oxygen being injected, with oxygen bulb icon in the exhaust gases . 4 - Practical Mounting 1 Material - Copper plate (phenolite) 2 - ferric chloride 3 - Pen you draw tracks for transparency (OHP) 4 - Box for housing the plate 5 - Wire
Eletrnicos Component 1 - LM 3914 2 - 2.2 micro Farad Capacitor eletroltico / 16 V or higher 3 - Red Led 2 (- Resistor 330 ohm / 1/8 w 4 - Trim Pot (Potencimetro) 4k7s 5 HIGH GLOSS) 6-2 yellow LED (HIGH GLOSS) 7-6 Green LED (HIGH GLOSS) 8 - Socket IC 18 pin
(Copy this side to the plate) 1 - CUTTING BOARD ON DESIRED SIZE 2 - WITH A piece of THE STRAW (BOMBRIL) bulb icon POLISH ON THE SIDE OF A copper-plated surface AT THAT STAY WELL glossy ES / grease stains bulb icon 3 - DRAW ON THE SIDE OF THE TRACKS copper-clad circuit bulb icon with a marker pen. 4 - DRAWN APS BOARD, PUT ON perchlorate, AT THAT ALL THE REST OF COPPER BE EATEN BY ACID, TAKE CARE THAT IN CONTACT WITH SKIN AND IF HAPPENS, WASH IN WATER CURRENT . Perchlorate Information This LARGEST ON BEING THE PRODUCT PACKAGING. 5 - AFTER READY, GO AGAIN BOMBRIL, THAT TRACK STAY POLITE AND WELDING EASILY GET IF WANT A PROFESSIONAL APPEARANCE IRON ENAMEL GREEN. . 6 - NOW WELD THE COMPONENTS AS THE CHART BELOW, bulb icon IN THE TRACKS LET intersect AVOID excesses Pay attention: - the capacitor identified by the positive or negative side that is in its carcass, some have only positive only other negative. - LEDs also have a own hand, with the cathode (positive) bulb icon identified by the bevel on one of its sides. - The integrated circuit (IC) LM 3914, also has its side identified by a cut or just a point at the top of its surface - Resistors have the sides (whatever the posioa be placed) - Signal (for corsa) must be connected directly to the purple wire from the lambda probe. - For a more precise adjustment use the potencimetro, it can vary from one led to more or less let the preference among
Do not forget GREEN: IDEAL MIX RED: YELLOW POOR: RICH MIX At work: and now!!! - Do not forget the position of the components. - Before breaking the plate, check the connection of the wires, see if Esto connected correctly and has no bad contact. use the old wires may be broken inside, always have a multimeter on hand. - Why when I light the lighthouse apparently the mixture decreases. Normal a small oscillation? When you turn the headlights blend actually becomes poorer, because the generator bulb icon suffers an overhead weighing bulb icon w / the engine, detailed very large oscillations may indicate a bad grounding done, positive and negative must be connected directly bulb icon on the battery if you want to leave right on the problem, the minimum consumption and may be connected bulb icon over years without harming
