TURNIGY AERODRIVE MULTI-FUNCTION DC WATT METER - RC Universe

TURNIGY AERODRIVE MULTI-FUNCTION DC WATT METER
I found the instructions that came with the meter difficult to follow, therefore I put this together hoping it
may help someone else.
Below is a picture describing the different components of the Turnigy Aerodrive Multi Function DC
WATT METER.
The second page gives sample wiring diagrams to test a battery, ESC/BEC and Motor combinations for
best current draw and wattage.
At the end, there is two pictures of the Watt Meter’s display screens.
Please let me know if you have a better way to describe what this meter’s controls. If you find any errors,
please let me know as well. Thanks
See second page for samples of hooking up the meter.
I hope you find this useful.

Multi Function DC Watt Meter
ESC/BEC PWR SWITCH
Allows 5v to red wire to
plug when needed.
Normally not needed.
PLUG FROM ESC
Normally would plug
into throttle channel
FROM BATTERY
Careful - Reversing
polarity will damage
unit !
Used to supply 5v
to red wire below
when plug requires
5v.
This way for no
5v to plug red wire
below. Typically
this way.

Switch setting when
testing a setup where
ESC/BEC supplies
power to Rx through
plug below. For testing
purposes 5v is turned
off since this unit has
its own internal 5v
and does not need
the ESC/BEC 5v.

WIRING AND SWITCH SETTING FOR MOTOR TESTING - Rx AND MOTOR EACH HAVE THEIR OWN POWER SUPPLIES
REASON RED WIRE IS CUT
When using a separate
battery for Rx, their will
be two Rx power sources.
One from the ESC/BEC
and one from the Rx
battery. To prevent
problems between the
two voltage sources, the
red wire from the ESC/
BEC that plugs into to the
throttle channel is cut.
PLUG FROM ESC
Normally would plug
into throttle channel
Switch Setting when
testing an ESC/BEC
setup where the Rx
in the plane has its
own battery, and
the motor has its own
battery. Red wire to
the ESC will be
cut to eliminate 5v
from ESC/BEC going
to Rx.

the screen and the second displays watts on the screen. Also shown is the Hobby King K1
RPM-KV meter attached, both are mounted on a piece of plywood and wired together
since I always use them together.
