The TURNIGY watt meter is a very accurate R/C amp/watt meter.
Predict model airplane flight time with any given propeller. Ensure peak currents are safe for motor, ESC, wiring and connectors Check battery health and performance. Evaluate R/C battery charging efficiency. Choose the best propeller or gearing and the most efficient motor Check for wiring and connector power losses Measure power and energy consumption of ANY device with a battery
Operating voltage: 4.8~60V (0V with optional auxiliary battery)
IT means the device gives you the information you need to predict your flight times. If you know your current load at full and half throttle, then you could predict flight time based on your battery size and flying style.
Guys, I need help. I have connected WM to battery and an ESC. It is showing zero readings at all times. Even after I have turned on the motor, all readings were "0". Wiring was done like in manual... Anybody with the same experience?
Does anyone know what will happen if the reading goes over the 130A rating of this meter? I have an EDF that should peak at 168 amps and wondered if it still reads or shuts off or what. Its says it will go over 6000 watts on this meter, i was hoping it would continue to read watts even if it may max out on the amp reading. Victor
I have one of these.
how can you test how accurate it is because of the following situation.
Mega motors say their test data on two motors I have should be 80 amp at 3s 65c lipo on 8 x 7 prop.
But watt/amp meter indicates 120amp at above manufacturers tests.
Which is correct? Is the watt/amp meter showing correct amp draw or is it over reading?????
These are accurate enough for hobby use. And great for measuring the difference between props. There could be several reasons why your data doesn't match the mfgr. But i would take the measurements seriously when choosing esc or prop. I use ecalc and for the most part the numbers are good enough to choose a starting point, then i check it with the watt meter. I also have seen mfgr numbers that don't match mine. If your concerned, contact the motor mfgr with your issue.
it work's great nice blue backligthing makes it easy to see for us night flying guys. the only thing i would like to see is longer wires on the meter. mine were only about 3inches long 6 would be good. 4 stars for the short wires. still good for the price.Thank's HK
This box toggles through the several measurement parameters. The parameter can not selected individually. However this works also. A little bit bulky to go fly with it. Especially on a 450 clas heli. No problem to fix it on a 500 class w/o canopy. Nice gadget every enthusiast should have :-)

Great meter, had some problems at first, but it all worked out. Turnigy is a great company!
