WATT METER

This function measures Current (Amps), Peak current, Voltage (Volts),
Power (Watts), Energy(Watt-Hours) and Charge(Amp-Hours) values for
you, in real-time, for the circuit in which you connect it.

Now you can stop wondering what's going on with your electric model
and get answers that allow you to apply science to your hobby. The
precise measurements you collect will help you fine tune your model
to get all the performance that you paid for.
With watt meter function, it is now easy to determine things like:

Flight time
Current through an ESC and motor
ESC, BEC and motor efficiencies
Charge put into and removed from a battery and the performance of
battery chargers
Battery health
Why power is lost during acrobatics or extreme conditions

i-Meter is activated when the battery is connected to the unit.

Press ‘MODE’ to select ‘WATT METER’ function
Press ‘ENTER’ to confirm selection

PRECAUTIONS
1. Do not leave a cell connected to the i-Meter for more than five
minutes.
2. Be aware that although the i-Meter only takes small samples from
the battery pack, the voltage will be reduced. Make sure you check
your pack balance.
3. Avoid plugging the cell in reverse polarity. The i-Meter can cope with
a reversed connection for a few seconds but it’s still better not to do
it in the first place.
4. Do not connect more than 5V to the cell inputs, again, the IRM can
cope for a few seconds but it’s best not to do it!
