Description:
- 100% brand new and high quality
Features:
we adopt 0.36in digital tube, suitable for 1~8 cylinder autos and motors 12V engine.
Our products are with shells and shine brighter.
Display battery voltage before and afrer engine start
When 12V car battery over voltage (overvoltage) or undervoltage, it will be
flashing alarm.
When battery voltage is less than 11V (< 11V ), or hgiher than 15V (>15V),
it will flickering alarm and display the real battery voltage.
Specification:
Working Voaltage: 8v~17v
Working Current: 40mA
Voltage Accuracy: ±0.1V；
Rotating Accuracy: ±30round/min
Maximym Rotating Gauge: 100-31800round/min
Bulb Color: Red
Quantity: 1 Pc
Other Fixtures:
1. This Auto car RPM meter 2 in 1 function meter use Ultra bright 0.36 inch
digital tube digital display instrument, driven by high performance mcu. Can
be used in automobile, motorcycle and other electronic ignition vehicles.
Using high integrated design, the size and appearance of the same size as
the single function of tachometer. Can be easily installed in the card into
the supporting housing.
2. Behind the instrument button is for adjusting internal parameters, when
it is discovered that the display speed and actual speed inconsistency ,
then we need to adjust the parameters (motorcycle idle 1100-1600, idling
750-1200, engine idling in the just started on the high side, hot car
stability decreased, such as air conditioning load change will influence
idle).
Parameters depending on the type of engine (such as the horizontal bar,
steel, four cylinder), distribution, and wiring position are concerned,
specifically according to the parameters in more detail below as a
reference. The parameter mismatch phenomenon is displayed, and the speed of
the actual difference, are integer times or several times. This reset the
normal parameters on it.
Before installation, please kind carefully read the following details,
problems timely and contact customer service. We are very happy to your
answer to problem solving.
How to adjust the rotate speed parameters if the real speed is different
from the display speed
long press button for more than 3 seconds to enter setting state, short
press select frequency, long press more than 3 seconds to confirm , ,
then it is ok. The parameters are saved in the internal chip, even if the
power cut and parameters donen't lost.
this meter default parameters is 2
2.1 Parameters: adapt to the frequency of 8.33Hz/1000 RPM per cylinder
ignition EFI car use.
2.2 Parameter (the default setting): suitable for frequency 16.66Hz/1000 of
four - cylinder EFI (second igniter) and two-stroke and four stroke
motorcycles.
2.3 parameters: three cylinder cars for the use of frequency 25.00Hz/1000
rpm
2.4 parameters: four cylinder cars are suitable for frequency 33.33Hz/1000
rpm turn (with electric cars) an igniter.
2.5 parameters: eight cylinder cars are suitable for frequency 66.67Hz/1000
rpm turn.
2.6 parameters: six cylinder cars are suitable for frequency 50.00Hz/1000
rpm turn.
3. This meter displays car engine speed automatically. When car engine
started, it begin to show the speed. If battery over voltage,which is bigger
than 15V(>15V)
The meter display speed will be flickering and flashing, which is alarm. and
notify you this car battery voltage is over. If enginer speed over 10000
rpm/m, for example 15000r/min, the car tachometer will display -150
4. Working Volt :DC 8V -17V
Current :40mA
Voltage accuracy: +/- 0.1V ;
Speed accuracy: +/- 30r/min
5. How to wire:
Black wire : Ground wire, connect battery negtive output (DC - )
Red wire: Power supply, connect battery positive output (DC +)
Yellow wire : Speed signal cable, connet to ignitor outlet or trigger lines
6. Installation guide :
6.1 Please connect Red and Black wire in advanced to make sure display is
normal to work then you connect other wire. Attention!
6.2 The speed signal from the engine ignition signal, can have many wire
connections
6.2.1 . Electronic tachometer wire (some car models have a on special wire
for speed, if connect, will have the best quality signal)
6.2.2 The high voltage ignition coil inlet wire (if car have no special
speed line, we advise connected here)
6.2.3 Ignition outlet wire
6.2.4 The ignition trigger inlet line
6.2.5 The trigger coil outlet
Because of each car line is not always the same , above all wiring position
may be varying degrees of interference ,result the speed signal is not
stable,
If your car model have special electronic tachometer line,connect it and
signal will be absolutely no problem,So best choice is 6.2.1
if no have special electronic tachometer line, then connect high voltage
ignition coil inlet wire is also good.So second choice is 6.2.2
Very import Attention!!!
Never connect singal cable to high voltage of high voltage ignition coil
outlet wire. You will burn this auto car meter!!!
Note:
1.Please allow 1-3cm error due to manual measurement. pls make sure you do
not mind before you bid.
2.Due to the difference between different monitors, the picture may not
reflect the actual color of the item. Thank you!
