Hi, This device can measure negative voltage and negative current? It's to measure the regenerative braking on a ebike. thanks
 Frederick 1 points
for that purpose you'd need to wire it in a circuit using diodes to have normal current bypass the meter and reverse current go through the meter. The diodes would impose a voltage drop and thus reduce power available .... Better to find a device actually designed for the purpose. They are made but you won't find it here.

This product unfortunately won't do that as it requires some of the power going through the circuit to operate and doesn't like being plugged in the wrong way

The GT Power version of this product is on Ebay for only $12AUD with free postage. Much cheaper and i think the GT power Ver.2 is more accurate than the Turnigy.

they are exactly the same, different face plate.

Yes, Same internals same build, But from what i have read and seen, The GT is slightly more accurate, So they must calibrate the GT differently. I don't know what they do, But the GT is better, And cheaper!.
 Frederick 1 points
Cheaper... IF you actually find a supplier who will deliver it instead of taking your money and you never hear from them again. E-bay = scam-bay.
 Richard 530 points
You may be right. All of my measuring is done to compare propellers on motors. So I don't feel like absolute accuracy is that important. When I compare the GT to my Beckman they are within .03v at 12v

Can this wattmeter record the maxium values?? I need to install it into my boat . thank you
 Richard 530 points
it holds the peak values until it is disconnected from the battery.

yeah, thank you, I need to know exactly this.

Might consider the Eagletree logger or similar which will give you a graph of data over time.

How does it tell abt flight time
 Richard 530 points
there is no flight time, it isn't really meant to be left in a plane. Good for static testing. It does show total Ah and Wh.
 Baqar 32 points
It is written in specs that it can predict flight time
 Richard 530 points
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.
 Baqar 32 points
How do u know that current load is full
 Andreas KarnÃ¥ 9 points
It shows the times the current draw is over 1 A.

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?
 Richard 530 points
make a little video, send it to customer service, get a credit.

customer service in HK is really bad.

Oh cut the wires already to same length. Probably the cheapest wattmeter on the market.

A little too big to mount anywhere on my cars. So, just relegated to pit tuning. Fun to watch anyway.

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 :-)
