How to setup a Digital Volt Amp Meter

[@TC-hl1ws]

Out of the numerous KZbin videos describing how to wire this meter this is by far the best instructions. Thank you.

[@gfmoore]

Yay! 😁 Yes please show what to do with the shunt, not that I need it, but one day perhaps. I think I'm going to put some coloured heat string around the thick red cable to remind me that this isn't going directly to positive, but is a continuation of the negative wire to the device. I'm using mine with a TTL breadboard computer and it shows my 5.00V and 0.092A - perfect.

[@ccv3237]

Very well explained. All details covered. Thank you very much.

[@rogerwood4149]

Hey mate. Did you say you had a video on how to set up one with a shunt. Be keen to see it. Just can’t find it.

[@luftkrabbe]

Thanks Scotty, mine had no diagram so this was just what I needed.

[@yoramalon5273]

Since electronics nowdays are much cheaper/easier to buy ready made , rather than building it yourself, making films on simply wiring electronic products, is very useful indeed. Wiring Timing modules with/without microcontroller, wiring remote controls modules, wiring gain amplifiers, turning a N.O shut down into a pulse...

[@larrypridgen4785]

Hi Scotty, Great video. I am building a bench power supply and I am trying to find out how to connect this meter to a 50 amp shunt and a DC-DC 300W 20A Constant Current Adjustable Step Down Module Buck Converter. Can you help?

[@_RandomPea]

wish there was a way to search through comments as i'm sure someones asked already. I dont have the visible shunt on the board but the ad said the shunt was inbuilt, its model DSN-VC288. following the diagrams above, all i see is the voltage. weirdly, if i just plug the battery direct to the meter black and red it shows something in the Amps counter.. any idea what gives?

[@samTollefson]

Question, I am using a single power source for my meter but I want to be able to turn off the meter while leaving the line power on. Do I interrupt the yellow wire for a switch?

[@graftedin3]

Thanks so much ,very clear diagrams. Tommy

[@Fifty26Nov2011]

I got one of these from a friend with 20A capacity. There is no shunt, just the empty terminals where your shunt is. Do I need an external shunt for this?

[@user-mr3mf8lo7y]

Hi, say I decided to set up as described on wiring diagram #1. Have a reliable power supply (herein SUP1, up to 30V, 10A). Powering the meter from a switching module (herein SW5, 5V) plugged into the same supply (SUP1). Ultimately, SUP1 powers LOAD and SW5. May be ignorable but; theoretically, would the meter measure ampere of load properly or a bit less as all are on the same power source? Thanks,.

[@yadawarinsawangwong2032]

Thanks to. your video I was finally able to get this meter working.

[@LA-Creative]

Thank you for this video! You have the best diagram I’ve seen of this meter yet (and I have been searching for hours)! 😅 The model I have looks just like yours but it does not have the built-in copper shunt. Not sure what to do about that (?) but I got the meter to at least read volts and current with this video (not sure if it is accurate without shunt tho). 😂

[@TruePatriot59]

How would I set it up in my boat to see how much my electrical amps are being used?

[@elk3909]

how do you make a mount for these to screw them to a board?

[@jamesallen6007]

Many thanks for this.👍😷🇬🇧

[@ScottyDIY]

No problem, Glad it helped

[@Mr_natenut]

Can it be hooked up between battery and charge controller?

[@jan-fredrikkrafft8538]

I have a question for you. I just bought a digital Ammeter for my boat (12V) showing V and A. For the measuring range, on the package it says 0 - 100A, but on the wiring diagram it says 0 - 10A…(?). It also says that red wire should be connected from battery (+) to ammeter (+) and from ammeter (+) to a DC loads (+) Then from battery (-) to ammeter (-) and a green wire from ammeter (third connection) to DC loads (-). I would like to measure the total consumption going out of the battery in A and voltage when engine is not running. - is this possible? - if I connect battery (+) to ammeter (+) and battery (-) to ammeter (-), then the green wire from ammeter to battery (-). Would this work? Thanks a lot for your answer!

[@funnyworld5482]

I am trying to understand how I can simply measure the output voltage of a circuit. On the input of the circuit board I would have example 12 volts DC 2-amps. How can I measure the output of that circuit to get a volt and current read. I am using LM2596 DC-DC buck convertor I want to measure only the output. The LM2596 DC-DC buck convertor has a variable pot that I can adjust for desired output voltage I want to measure

[@Nathan1975Liggy]

bit confused how do I add this to an existing PSU? I take it both reds and yellow to supply + output and both blacks to supply - output.

[@Lord5oth]

thank you, thats very helpful

[@CogWorksCreations]

Instead of having to back the video up to show the max Amp... is there a way to put a second display on this to store and show the max Amp?

[@collectorsinfo]

Thanks for this, nice & clear.

[@ScottyDIY]

Cheers, Glad it was helpful!

[@ronjones4069]

good stuff, thanks, but your computer display is blurry. Otherwise, excellent and thanks. It really helped me.

[@markadriantagudin3866]

Can i use this to my 72v charger to see the current charge of my battery?

[@pattayaguideorg]

Ur a champion mate.

[@basmaal-ghali9174]

Thanks. is there any way to troubleshoot it? I bought a new one and the screen does not work!

[@ScottyDIY]

Hey, not really I would try get your money back if I doesn't work and get another, you could pull it all apart and try and hopefully find a faulty component but it would take awhile and they the cost to replace that faulty part.

[@basmaal-ghali9174]

@@ScottyDIY Thank you

[@boprosplumbing]

Thanks for the help. Mine wasn't working, used your diagram and it still wouldn't read amps THEN I realized I had soldered extentions, but never actually plugged in the connector lmao but it works wired by your diagram

[@osmancanbaz7312]

Would yolu tel me what is taht after diod 5228A

[@waterfuel]

Can the cheap China digital meter be used on negative volts and negative current , by switching wires around???

[@mkepler5861]

thank you, that was very helpful!!!

[@condor5635]

I’m using two of these right next to my circuit panel on my 120 V house wiring the project box which has 120V draws 45 mA. How can I fuse that to protect the wire and project box? Can you put it inline 100 mA fuse?May not be necessary but if it’s easy to add a little fused to protect the wire from short circuit that would be nice. Thanks

[@ScottyDIY]

Yeah inline on the active is fine. Not sure if you can get a fuse that small. Maybe even a PTC might be more suitable.

[@condor5635]

@@ScottyDIY - I see 100 mA glass fuses for 120 V available. I guess all I was wondering is do you just put the fuse in an inline fuse holder like you do for a car? I’ve seen similar fuses although larger for microwaves so I’m guessing the answer is yes

[@ScottyDIY]

Yeah that will work, their should be a few different types of fuse holders depending on what suits you project box, Like a in-line or panel mount.

[@H35HRO53]

​@@ScottyDIY would very much like to see the vid you suggested describing an external shunt connection, alternatively would it be possible to just increase the mass of the internal shunt to read more amps? Hope you see this, great vid many thanks..

[@depatrick]

thanks a lot! so simple.... if you know what to do :)

[@iancarter4999]

I'm a bit of a numpty with electrics. I want to setup an Ammeter on my bike based Trike. Simple connections for voltmeters I'm okay with. Its just how I can wire in an ammeter to the bike charging system.

[@frankprah5704]

Thank you

[@batsrule]

Thanks

[@ScottyDIY]

No problem
