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)
I connect my turnigy watt meter to ebike 54v 5A lipo with22a 60v max. controller. peak amp suppose to see 22a but my wattmeter reads only 0.77 amps and because of this watt calculation also wrong. is it defected? think it is not working properly. Any suggestions?
It's possible that you have a defective one, but it sounds like you may have the power connected backwards or a short between the input and the output. This meter measures the current with a small resistor between the two black leads. Make sure you don't have both sides of the circuit grounded, bypassing the meter.
You can test this with a 120v incandescent bulb. Make sure it's not fluorescent or LED. A 60w bulb should draw somewhere around 0.25 amps at 54V, although it will be a little bit higher since the bulb won't be warmed up.
Also, as someone else posted, there has been at least one shipped with the label on backwards, so if the numbers are upside down, then your source and load will be reversed as well.
Hi, Does this wattmeter tellsyou the amount of charge left? Like in case of HK-010, it tells you the amount of charge left (as percentage) for LiPo batteries, does the same thing happens for this wattmeter? Does this meter has the pins to collect the LiPo's balance plug? Both the questes above are related.
Also, has anyone an idea of accuracy of this meter against HK-010?
Would appreciate reply.
I use these meters to measure the output of my solar panels. To keep the readings after dark I connect the aux to my 12 storage battery. As the number of my solar panels increased I found the meter was not able to log the total watt hours for the day, so I decreased the current thru the meter by adding wire shunts across the negative lead of the meter. The meter reads current in the negative lead. My meter required about 15 inch of 12 AWG or 24 inch of 10 AWG to cut the current reading in half. I trim the shunt by putting another meter in series and cutting the shunt on the meter I am calibrating until it reads 1/2 the amps of the other meter in series. This means all amp and watt readings need to be increased by a factor of 2 to get the correct reading. After adding more solar cells I had to add two more shunts, reducing the meter reading to 1/4. This was done so I could take daily readings on my system at the end of each day. This does not affect the voltage reading.
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!
