1. Double-sided tape installation:
Proper position requirement: No moisture, no grease, is a plane, no violent
vibration, and the temperature not exceed 125 F.

The test after the connection: Start the engine, the LCD of the tach
hour meter displayed the RPM and timing, which means the connection is
correct. If the RPM is inaccurate, please refer to clause A to adjust the turns
of the winding, or set the type of the engine (more information will be provided
in the following instructions).
C
b) Choose a location where the pick-up wire (included) will reach the meter
to the spark plug.
c) Install with screws as the below diagram.
a) The design allows for either a flush panel mount or surface mount.
Red signal wire connection: Wrap the red signal wire around the spark
plug, wrap it 4 to 5 turns, and fasten it with a cable tie to ensure it is effectively
fixed and will not loosen. (If the connection is not strong, the tachometer will
get insufficient signal, then the RPM and hour values will be inaccurate.)
a) For traditional ignition modes, wrap red signal wire 4 to 5 turns tightly
around the engine spark plug wire.
b) For "pencil coil" ignition, wrap red signal wire around the plastic coil above the
spark plug.
c) The spark plug signal generated by different engine types has the difference of
strength and weakness. By adjusting the turns of winding, the appropriate adjustment
can be made to improve the accuracy of the RPM and timing data. This is a skill that
different degree spark plug signal that allows the induction wire to acquire.
2. Screw installation:
3. Signal wire installation.
Note: Proper position requirement: no moisture, no grease, is a plane, no
violent vibration, and the temperature not exceed 125 F. Do not drill into gas
tank, engine crankcase or oil reservoir frames.
Under normal condition, if the RPM is a little low, you can
increase the winding turns, if the RPM is a little high, you can
reduce the winding turns. For example, wrap 6-10 turns, if the
RPM is a little high, you can reduce the winding turns. For
example, wrap 2-4 turns, if the RPM is a little low, you can
increase the winding turns.
Connect the black shielded wire’s terminal to
the ground, the connection place can be the
metal casing, frame, ground or chassis of the
engine.

Product Operation
a) In order to meet the usage
habits of different users, the
program of this product has 2
sets of use systems (just like
after the WINDOWS system
can be used on the apple
computer, the user can switch
to use the WINDOWS system
and the IOS system),
respectively, DSP-1 and DSP-
2, the default system of the
product is DSP-1.
a) Push "MEUN" button continuously until display the "TOT" (interface).
b) Press and hold "SET" button continuously until display the "DSP-1"
or "DSP-2" icon, release the "SET" button, and it will automatic return to
"TOT" interface, and you have selected the system needed in this way.
(Note: "DSP-1" and "DSP-2" is cyclely selection.)
b) The difference between
DSP-1 and DSP-2 is that the
display mode is different. All
functions of DSP-1 are
directly displayed, while the
function of DSP-2
distinguishes between time
module and RPM module.
These two modules can be
called separately for display.
The functions of DSP-1 and DSP-2 are shown as the following diagram：

a) When the tach hour meter detect the engine spark plug signal for
more than 1s continuously, the LCD will display the current RPM of
the engine.
b) The RPM will be refreshed every 0.5s.
c) The RPM can be programmed for different pulses per revolution;
Different programming setting will get different RPM; Please follow
the instructions in section 2 below to programming setting for
accurate programming.
This product provides 9 programmable firing patterns, which can be
selected according to the corresponding relationship in the table below.
Note: Some 4 stroke 1 cylinder engine is 1P1R, the setting is the same
way as the 2 stroke 1 cylinder engine.
