Chinook G2 Elite Optical Tachometer - Manual

Operation Cont’d:
Tachometer RPM Reading Guidelines:
NOTE: When achieving the correct RPM reading for either a 2,3 or
4 blade system helicopters, it is possible to see a blurred image of
your model’s rotor blade at half of the actual RPM speed. In this
case, try increasing the Chinook’s RPM setting to approximately
double until you see a clearer image of the rotor blade, the LCD
screen will then display the actual RPM reading. On average, 2
blade electric helicopters have an approximate hovering RPM
speed of 3000-3300 RPM and nitro/gas helicopters have RPM
speed of 2000-2500 RPM.
5. Use the RPM dial to match the Chinook’s RPM reading to the
helicopters RPM head speed while viewing through the viewing
window on the device. While viewing through the viewing window
directed at the R/C helicopter models rotating blades, the Chinooks
LCD screen will display the actual RPM speed of the helicopter’s rotor
speed. The Chinook will function with right or left hand rotation rotor
systems and with most multi-blade systems.
6. (For Elite version only) Press and hold on the dial switch and release it
once the LCD display flashes the rotor blade number and this will scroll
the RPM readings for either a 2, 3 or 4 blade system. Repeat to scroll
through the other blade counts.
7. To save current RPM setting, press and hold on the dial switch until the
LCD display’s flashing rotor blade number has passed and displays
“RPM saved”. Now every time the Chinook powers on, it will default to
your saved setting.
8. When the Chinook is not in use, it is recommended turn off the power
with the I/O switch to the off position to prolong battery life. A low
battery strength indicator will be displayed on the second line of the
LCD screen as LOBAT. This indicates that the 9V battery should be
replaced or recharged.
The dial switch increments and decrements the RPM speed by 10
RPM. If the R/C model blades drift very slowly from the window
readout, the LCD screen will display the actual RPM reading within 10
RPM.
To achieve the correct RPM rotor blade speed of your helicopter, it is
recommended to initially set the Chinook RPM setting above the
assumed hovering RPM speed of your helicopter. Then you will look
through the Chinook’s viewing window and decrement its RPM speed
until you see the same number of rotor blades rotating very slowly. For
Elite version, please adjust the Chinook for either 2, 3 or 4 blade system
to match your model’s blade count before attempting to achieve the
correct RPM reading.
Working in close proximity to the R/C helicopter will result in visual
distortion of the rotor blade causing a “boomerang” appearance which
does not affect accuracy.

Congratulations on your purchase of the Chinook Optical Tachometer G2.
The Chinook is designed and manufactured in Canada with the state of the
art micro-controller technology. Its universal design enables it to determine
the rotor blade speed in Revolutions Per Minute (RPM) of any R/C helicopter
model with an aid of a large visual viewing window and LCD screen. It’s uses
high quality robust components that guarantees the accuracy and
optimization of the head speed in any condition.

On/Off power rocker switch.
PackageContents:
HardwareSetup:
Operation:
1. Switch the I/O power switch to the 0 (OFF) position. Open the battery
compartment located on the back of the Chinook unit by sliding the
compartment lid towards the bottom of the unit.
2. Install a 9 volt battery (sold separately) to the enclosed battery clip
located in the battery compartment and gently place the 9 volt battery
inside. Ensure that the 9 volt battery is sitting comfortably inside the
compartment to avoid the battery compartment lid of closing
improperly. Replace the battery compartment lid by carefully sliding
the lid back on.
3. Your Chinook Optical Tachometer G2 is ready for use.
1. Turn on the Chinook Optical Tachometer G2 unit by switching the on/off
rocker switch located at the top of the unit to the on position I.
2. Wait for the rotating disk to wind up and the greeting message on the
LCD will disappear.
3. The Chinook will normally default to 2500 RPM if the
device has been used for the first time. If no activity is given to the
device within 2-3 minutes, then the device will go into “Idle” mode. The
LCD screen on the unit will display “Idle”. By pressing the dial switch
located on the front of the device will cause the device to wake up and it
will resume to the last RPM setting.
4. Sliding the dial switch either up + or down - will adjust the Chinook’s
RPM speed reading and the rotating disc will adjust accordingly.
Sliding it upwards will increase the RPM speed while sliding it
downwards will decrease the RPM speed. By holding the RPM dial
speed up or down for more than a few seconds will increase the speed
of the increments of the RPM adjustment for a faster response.
