Setting Engine cylinders
(IMPORTANT please read)
The tachometer is factory set in
demonstration mode
.....
If you power up the
Tachometer without setting the cylinders the pointer will automatically start
moving
.
Set the cylinders as follows:
1. Press & hold the switch
!
!
!
!
!
and apply power to the tachometer.
2. Release the switch
!
!
!
!
!
when the pointer has stopped resetting on the stop pin.
3. Press the switch immediately
!
!
!
!
!
to select the number of cylinders - the pointer
will move to show the number of cylinders selected.
e.g. Press 4 times for 4 cylinders (pointer will point to 4000 RPM)
4. When the desired number of cylinders have been selected wait
"

3 seconds
and the tachometer will resume normal operation with the new setting.
5. To check the setting repeat operations 1 & 2 above, the pointer will move to the
selected number of cylinders. After 3 seconds the unit will revert to normal mode.

Note: For 2 stroke ignition systems set the cylinders to double the actual number of
cylinders.
For multi-coil ignition systems use the tach output provided or connect to one coil only and
configure the tacho for the cylinders the coil fires.
When using a dedicated Tacho output check the number of pulses per engine
revolution :- 1 pulse per rev = 2 cylinders (4 stroke) = 1 cylinder (2 stroke)

Tell Tale Memory
The pointer will initially move to the highest RPM value, then
after 5 seconds the needle will move to the full scale of the dial
and sweep down to zero.
Only when the pointer reaches zero will the memory be
reset
.
Normal Operation
When power is applied to the tachometer, the pointer will reset moving backwards
against the stop before moving to the current RPM (Zero RPM if the engine is not
running). When power is removed, the pointer is held at its’ last position (it doesn’t
necessarily return to zero)
Press and hold the switch as if you were to reset the Tell Tale
memory (see section above).
When the pointer sweeps down to zero - resetting the Tell Tale
memory, continue holding the switch for a
further 5 seconds
.
The pointer will then move to the current setting for the Shift-
RPM.

The pointer shows the highest RPM seen since the memory
was last reset

Note: The Tell tale will be remembered even when the power is off.

Release the switch. Now each time the switch is pressed or
held on the pointer will increment 50 RPM. If the pointer
reaches full scale it will return to zero and start to increase
again.
When the desired Shift-RPM has been reached, release the
switch and wait
3 seconds
. The pointer will then move to zero,
indicating that the Shift-RPM has been set.
Note: The Shift-RPM will be remembered even when the power is off.
