Thank you so much for this video, and the derailed breakdown of this device. It really helped me out on having to figure out which wire goes where.

[@604smit]

thank again Robojax, Just one week ago received this meter from China and now you have this review, timing could not be better😊

[@robojax]

You are welcome Leo. I am glad you found it useful.

no problem.

[@moking8095]

Hi All I have spent a little time on this problem and finally twigged that the tiny unmarked X in thick red wire was in fact the most important item, namely the load. This all now makes sense.

[@NsndoBrasil]

Can I use a 12Vac output with diodes and capacitor to make a 12 volt source with CI LM7812 to power the lighting of this Module (Deek-Robot Shield Mod.BL-01)? Note that this derivation is from the same transformer that I made the variable source from 0V to 50V!

[@laurikranz3469]

Obrigado

[@robojax]

de nada.

[@ibzanypava9863]

Hello, I thank you for sharing, I have achieved this instrument but I have not managed to make it work well I have seen the video but I do not understand some words because I do not speak English and I would like to ask you the favor if you can give me indications of the written connections, either in English , to translate them into Spanish. you have a subscriber you are the only one who gives explanations. Very thankful.

[@robojax]

You are welcome. snipboard.io/x80ryg.jpg

[@ticktock8751]

you can wire the meter off the same voltage supply, what i am trying to say is you don't need another power supply to run the meter. its very easy to do.

[@robojax]

If you measure the current for a source less than 5V, the display with turn OFF. You need separate power to keep this working. Thank you.

[@ticktock8751]

@@robojax i am not going to go lower then about 7v so its ok

[@robojax]

Yes.

[@wachidintegal5180]

Hii... what can be replaced with a external shunt ....if you want a higher range measurement? Thanks sir

[@robojax]

Hi, here is using shunt with Arduino to measure up to 500A kzbin.info/www/bejne/rnnIaoWIhryAeK8 or use a module with shunt kzbin.info/www/bejne/qpjRloFond-Fm5I

[@beastcode2865]

Can you use external shunt to make the amp capacity higher?

[@robojax]

No you can't. you would need different meter. see this video kzbin.info/www/bejne/g57bqGqKZ56NbM0

[@tomb2623]

Good video! Is it accurate in 0.5v-5v range too ?

[@robojax]

Yes it is . But for very accurate reading you should get something that measures up to 10v or 20v

[@moking8095]

You show a stylized battery with the thick red and the thick going respectively to positive and negative. Unfortunately, the thick red and thick black go straight to the shunt which would soon short the battery out and burn out the shunt. I think you need to revise your diagrams.

[@Maersky-747]

I have the BL-02. What is the supply voltage/current needed to power the device? Can the device be connected to a 12v car battery and measure the voltage/current of the battery?

[@robojax]

this device can be connected to Car battery to measure the voltage. It can measure only 10A max. When you start the car, it uses about 400A or more if larger car. So this can't measure it. Of course if you connect a device that uses 10A or less, it can measure it in car too. What is B02? I did not find it

[@Maersky-747]

@@robojax The BL-02 is the same Ampere Power Meter you used in the review. If you look on the back of the circuit board you'll see 'BL-02'. That is the model. I have a device that draws 12v @350 mAh from a car battery. When the car battery is fully charged, I want to use my BL-02 to monitor the Voltage and power consumption for a month or longer, until the battery is flat. Can the Meter be connected directly to the battery or does it need a small load in place?

[@robojax]

Thank you for telling me the model. I will have to look at it. My answer is the same as above with addition, to measure Power, you need to measure the current.

[@edinfific2576]

I have read that the device itself uses under 15mA. The voltage is apparently 7-12V, but I would say that it can go at least up to 15V (it would have to go that high to work with a car battery). UPDATE: I have checked mine and the supply current is 10mA. The specs say 7-12V supply, elsewhere I've seen warnings about not going over 13V, but it ran fine for a month or two (until I replaced it with a better power meter; it didn't fail) on my battery which often got to 13.5V and very rarely up to around 14.4V.

[@jhonmcheaven3205]

If you put that in motorcycle where should you put the wire in load that all load will be calculate?

[@robojax]

I have shown in video two things 1-Power supply 2-Load. so whatever I said, for you 1-Battery and the 2-motorcycle is your load. Just follow that

[@sec.0991]

can it measure in the range of millie watts ?

[@robojax]

All features have been explained d shown. Please watch and get answer.

[@dj_sorra8605]

Can I put a 24v adapter with 6Ah and 100w instead of the 0-50v battery?

[@robojax]

of course you can.

[@dj_sorra8605]

RESPECT🙋‍♂️

[@Bergwacht]

Can I use this measuring device on my car? Supply voltage is described with DC 7-12V. But if the car's engine is running, there are 13.7 to 14.7Volts, can i use this wile driving?

[@robojax]

maximum voltage is 12V. you may have to risk and test it to see if it dies or not.

[@Bergwacht]

@@robojax more worse... I cooked my pv module with that thing lol tomorrow i will buy a bigger 320wh one.

[@Bergwacht]

@@robojax If I cook one of these it doesn't matter, I accidentally bought 5^^

[@robojax]

Yes. so what happened did it burn or not?

[@Bergwacht]

@@robojax there was a cloud of smoke. I think I didn't understand the instructions correctly (as shown here) When I put it like the one in the pictures, there was a spark, there was smoke and my solar system was done. now i have bought a new solar cell, but the pain runs deep - these things are expensive. In the circuit diagram of banggood, the 2 cables are brought together, the ampere test lead and the volt test lead. But when I closed it together, my solar panel burned out and the fuse on my expensive victron charge controller. So iam lucky now that i dont need a new 100€controller.

[@GladstonAlmeida8667]

Plz do video how to connect this meter to solar panels

[@robojax]

This is how it is done. I mentioned the load which is your load. I mention power supply which is your solar panel.

[@paolomichielin4849]

Una domanda. Dove c'e' la crocetta a sx, cosa bisogna mettere? Una lampadina? Se si', da quanti volt? Grazie per una eventuale risposta?

[@robojax]

Ciao, mi dispiace aver visto il video e non ho capito cosa croce. per favore menziona l'ora come le 3:50, quindi la guardo. Grazie

[@paolomichielin4849]

Il carico da collegare al voltmetro amperometro come deve essere? Intendo il filo bianco!

[@Pulverrostmannen]

I come to the conclusion these devices are extremely sensitive to ripple in the voltage, it just start to jump around in the shown values very easily, If the voltage and current is clean they show fine. otherwise they are pretty nice. I think the issue is that they have too high refresh rate

[@madhukeshnp]

Sorry to say... The volume is way too low. This is not the first time. Please change your mic or boost it up in the software.

[@xeroxene]

Robojax, I can hear and understand you perfectly. I had to turn the volume up 5% compared to the previous video I was watching. I am watching this on a television in a noisy room. Hello from Australia!

[@robojax]

MADHUKESH, I just discovered your comment. I have made some changes. Thank you for the tip.

[@robojax]

Hi Alpha, I missed your comment. Now KZbin have new tools that shows all comments I have not replied. Thank you . Hello from Canada.

Sorry I speak English and Farsi.

[@thagoson]

The connection of the DC 0-50V (input or output source?) as shown in the diagram is not correct since these two terminals which is connected with the red and black wires from this source is shorted together with the wire shunt and cause short circuit to this DC 0-50V unless the black cross in the circle is to indicate the red wire is not used, if so then it should not be in the diagram in the first place.

[@thagoson]

Apologize for my above comment on the diagram that I've got the image from the net. The info in your video does now make everything clear up now. Thanks for your good work.

[@robojax]

no worries. you are welcome. You can edit comment by clicking on the 3 dots that shows for each comment. good luck.

[@groovyone5492]

The white wire should be connected to the load side +...not the supply side +

[@robojax]

make sure to follow what I have shown. I have already burned ONE of these.

[@egeotomasyon]

Power (watt) indication is wrong ! 9:08 Voltage 21.8V, Current 10A, P must be 218 Watt. But indicator show 214 Watt !

[@robojax]

The device has refresh rate. It doesn't refresh quickly. It takes a little time. Also 5% error is normal.

Probably makes little difference as it is series, but your circuit diagram for the current is different from your physical hook-up....thing is, mistakes like this can make it difficult for beginners. Suggest you double check before posting.
