Turnigy 7 in 1 Mega Meter Battery Checker/Watt Meter/Servo Tester
Turnigy 7 in 1 Mega Meter - Battery Checker/Watt Meter/Servo Tester/Optical Tacho/Temp Gauge/Thrust Calc/Battery Internal Resistance Checker.
The Turnigy Mega Meter is THE essential tool for electric flight, this easy to use meter will ensure that any power train is optimised before use, it is able to not only give you watts/amps/voltage figures but the in-built optical tacho can also give you RPM figures in an instant, combine these features with the in-built Thrust Calc and you have total peace of mind that your model will perform before it get's into the air, no more guesswork!
Likewise, the battery checker not only gives you the usual overall and individual cell voltages, you can also check internal resistance and temperature for an accurate overall picture of battery condition. As if all this wasn't enough, there is also an in-built servo tester! If you only ever buy one Meter for your toolbox, the Turnigy Mega Meter should be the one!
I'm new to electric and was told that I need one of these. I'm mainly interested in the watt meter. Can someone explain to me how to read the numbers and how to apply the readings to my electric setup. Examples are best. what is Peak(c) is that the "C" on my battery ( 14.4 30"C" 2500mah) Dont want to exceed the "C" rating? And I have a motor that is 710kv (Turnigy G25) What number should I be looking at on my watt meter? PLEASE HELP
That's 87 watt hours. Watt hours are calculated by multiplying amps x volts x time. It's not really useful for much in terms of rc, other than being able to divide it by your battery voltage to give you milliamp hours and be able to calculate flight time on a certain size pack
Fyi

Some issues about this unit*
1-Tacometer problem:I was able to read the rpm of an electric motor indoor, but outside it did not read the rpm of my 10" prop connected glow engine.
2-Thrust calculator doesn't take the pitch of a propeller into consideration.The printed manual page 16 line 3 reads exactly "Practical tests revealed very little if any change in thrust due to pitch variation at the same RPM".The unit asks the CF (propeller's efectiveness coefficient) value which you wont see on most documents.
Help. Has anyone experienced this?
The LCD appears to work normally in servo tester mode, but my servo doesn't move at all. Tried with many servos. This thing does have a built in 5VDC regulator right? I tried with 3S and 4S input.
yes any function started only with battery on balancer connector connected. check polarity. servo - should be on the opposite of the little slot.
no matter on which is the s battery you use...
Yes, many Turnigy products are from the same factory as SkyRC, IMax, Toro and other manufacturers. They just have higher volume sales and lower profit margins.
You cannot make all the functins work together. However if you already have a thrust calculator rig set up, connect your meter and use it as a watt meter. Then you will be able to read volts, amps and watts.
On a model aircraft I place the aircraft (with wheels, obviously!) on a solid smooth floor, use a small digital luggage balance (HK sells similar) and hook that up to the tail using wingbands and then fasten the other end to something solid, then it will directly measure the static thrust.
Do be careful with the wattmeter, one careless moment when you plug the power leads into the input and output, and a reversed connector here will result in an order for a new ESC, plus some rewiring.
Does anyone know how to make all functions work at the same time?
I want to use this meter to a Thrust calculator rig but cannot use all the function at the same time.
Does anyone know how loud the alarm function is? I have been using a different one, but it's not very loud and I want it attached to my RC Car while I drive
Being .2 off is not asking to much from a cheep meter for a lipo .. A "dont ask for more " would be complaining about it being .001 off or .01 off ,but .2 on a lipo voltage reading is not just a cheep meter it is just ****.. I took it apart and there is a program header. but i am not good at code... However If they ar all like this the Product title should be" Turnigy 7 in 1 **** Meter " or in your case Turnigy 7 in 1 Cheap Meter "do not ask for more".
Who ever marks best answer should also change the specs for this product
"no way of adjusting. is a cheap meter that gives you an idea of the battery status. do not ask for more."
Dont think any one would buy...
sorry manny, I will not be so upset..I consider, despite spec and description (everybody knows the emphasis of the sellers...), this a not so bad product for the money. it gives you an idea of the status of your battery, balancing etc. provides you a servo testing and tachometer (when it works...). I use it daily and frankly I do not consider*****. if you need more you must pay more...thanks for your credit.
and how your optical tacho works? On mine, I can not measure heli blades rpm, it showed only peak 30 and no more. And on airplane propeler it showed number within 1000rpm difference when throtle was in one position and it showed it always only as peak when I pressed enter it did not show current rpm. And thermometer shows for example 50°*C when actual temperature was over 80°*C.
the optical sensor is not very sensitive and cannot register any changes in the ambient light, i tried it but without a external source of light it will not provide proper readings.
Hi guys! I have a question regarding contrast of display. My shows dark background along with text when switched on. So alpha-numerical info is not seen very good on this dark background.
Does anybody know if there are any hidden functions allowing to adjust contrast? Or this is hardware problem?
I would use a battery with an output voltage compatible with my servos, i don't think there is a BEC in this meter. (In fact i always use a battery with the correct voltage to test servo)
For the Battery Connections for current, what mm connectors are they using... can someone who has one measure it for me. thanks in advance. I just ordered on of these.
Servo tester - battery must be connected via balancing port. But then servo tester only moves servo back and for in automatical mode I can not see any valuable result. It does not show me the center, the pulse. So what for is this servo tester??
And thermometer does not work, it shows only up to 40 celsius though the device was 80 celsius hot. Does your thermometers work??
Yes,you connect a battery via the balance port.Press the "Enter"button in will then show the menu's,select "Servo Tester" and it should default to "Manual",in manual mode you can test the sweep of the servo and you can centre it if you set it at 1500 ms in the window.This is handy for setting up the servo's in your model without using your Tx and Rx.
No, what they write in manual is contact it to the servo tester connector, not to balancing one!!! And no warning what kind on battery do you need to use for servo testing!!!!
Hi guys, I have a problem with the mega meter:
Voltage readings in watt meter mode are significantly less then actual (with no load). A full 3S is showing 8V, 2S 5V, 4S 10V. I dunno whether it needs replacing, or can be fixed via any calibration or something.
I have placed a customer support request, but id like to see if anyone else has experienced this
I bought two of these and they are perfect. Assuming you have checked your lipos with a multimeter and or someone else's cell checker and it matches the 7in1 mega meter, it sounds like yours is faulty. Good luck.
connect a battery in the "in" port, select servo tester function and plug the servo connector in the related slot. use the potentiometer to move the servo.you can center the servo once you have centered the potentiometer.
oh, yes, servo is ok...but I connect battery via power input port not via balancing port...but it is my fault I did not read carefuly manual it has been said there. But nothing about that you have to connect only 2cell battery
To check the internal resistance first connect a battery to the meter through the balance connector on the left side of the meter. This will power the meter. Then connect the special 2pin plug cable to the input also on the left side. The two pin plug is then used to check individual cells of any battery through its balance lead.
You have to check individual cells. You cannot test the three cells in series. It expects that the voltage should not exceed the topped off voltage of a LIPO.
hi guys. i have notice that this mega meter and the original skyrc are not accurate on IR reading. i have messure some batteries with 100 mohm IR and when compare it with a Icharger ant turnigy smart charger are on 10-12mohm. my buddy have the skyrc version and also gave a very high reading just like my mega meter.
any way to calibrate this or any1 with this issue?
The meter gives accurate IR. I checked all my new batteries with it and had readings between 20 and 26 milliohms. These readings matched the readings I obtained calculated by amps and voltage drop on a known load.
20 - 26 mohm are very high for a new battery. should be reading somethig from 2 or 3 mohm depending on c rating and mah. Like the other post said is like a x10 reading error or miss a decimal dot.
Many variables can affect the reading. You would have to compare actual readings of a precision instrument to the reading of this meter to determine accuracy. You can't use the specified internal resistance of the pack.
info for the customers: it does not have an internal battery therefore an external power source is required eg when performing measurements like rpm. nothing special buy when I ordered I have not understood.
i just expect it has a battery inside to power all the tester function like RPM for example which by the way work qite bed.at the end is just a good battery tester nothing more...
plug provided are: one similar to servo wire for temp measurement plus one cable for IR plus 2 couples of cable with one side plug and the other side to be soldered to your preferred battery plug.
Buen producto. Integra TODO EN UNO. veremos las mediciones cuando lo reciba.Good product. Integra ALL IN ONE. measurements shall see when I get it.

All I can say is ... WOW Very impressed, the cell checker is really accurate tested with a volt meter, i have no way of testing how accurate the watt meter is, but seems to work very well. I have yet to test the optical tach, but for this price I woulda just been happy with a watter meter and internal resistance meter, having 5 more functions is AWSOME. Also smaller than I thought! Only time can tell if it'll last running all the voltage through.
This metter is great, worth buying!Everything you need at the field in one handy tool ! Smashing 5 Stars device !

Well designed clever meter. The bullet connectors are smart since you add your own preferred battery connectors and can swap the IN and OUT easily for load and charge tests.
Seems pretty accurate on current and as a wattmeter which is the big test. The other measurements are easy to do accurately. Uses a 1.0 mOhm sense resistor for current which is a lot more in-circuit resistance than the 0.2mOhm of the Emeter and similar quality Wattmeters.
Combines pretty much everything anyone would need and the screen is fairly readable (better than the PowerLog which is similar in functionality). The thrust measurement seems useless as it ignores propellor pitch on the grounds that it does not affect static thrust - really. Maybe I missed something here. The IR measurement is hopeless. Uses a roughly 0.5Amps load and two wire method which is useless for modern LiPos. I got readings varying from 104mOhm to 41 mOhm per cell on a 4S 3700 mAh battery as I watched. The actual IR per cell is between 3.96 mOhm and 4.20 measured with an ESR/IR meter!! Might be OK for comparative cell measurement but certainly not for correct IR values.
Overall excellent value - just don't use it for IR.
