Why does my Sunpro only show a -1 on all settings except the ohms reader where I cannot zero it and it goes crazy displaying different readings even without the cables?
Just bought a cheap multimeter off Amazon for a DIY project, but it shows a reading even with leads shorted. I've found that the cause is when direct sunlight hits the display. I think the multimeter is faulty and I will be exchanging/returning it, but do you know why sunlight would affect the reading? Regular light and heat from a candle does nothing, so I'd think it'd have to be some sort of ionization from the Sun that's affecting the meter (and it's not shielded enough).
I short the leads on my fluke 179 set to mv ac and is shows 0.5 after waiting about 15-20 seconds is this normal? Any help would be greatly appreciated guys 😊
I’ve got a Fluke 375. It is offset by -0.2V permanently. Can’t get it to zero. If I change to mV range via the yellow button, it shows around +400mV. Leads can be attached or removed, doesn’t matter. Shorting leads doesn’t fix. Very low use on this meter. Any suggestions?
Sheesh - thank you. Just bought a new one and was going to take it back and stick with my older DM22B that does not seem to wander so much. QUESTION - what is your comment on that Southwire DMM?? Thank you.
Got that. But in my case my caliper meter shows AC current reading of around 0.1A (not mA) even when the load is not yet turned on. That's quite significant for current.
My (very cheap) multimeter isn't doing exactly the same as yours- it is steadily increasing from the time I turn it on until I turn it off- starting at 0.1 volts and increasing up to several volts. I think the highest it went was about 4.5 volts- no millivolts- before I turned it off, but it was still climbing. No idea why it's doing this. And this is just minutes after it was giving me accurate readings. When it's glitching out like this, it doesn't register any real readings, i.e. I connect the leads to a battery that should be 12 volts, but the reading stays roughly where it is, still just climbing 0.1 volts at a time.
Oh boy you don't know how much money you just save me plus some round to homedepot for return body Thank you And I like your comparison with the fluke meter because the fluke meter N.A.S.A the Army of USA use it for accuracy and plus it was made here ect Once you pull that out and it was doing the same thing because the meters peaK up small magnetic wave in the air thank you
What does it mean if I put my leads together and it doesn't zero out does that mean it's not working correctly i got a brand new Innova 3320 two of them and they won't zero out when I put the leads together
I just bought a klein 450 and on the millivolt setting even when I cross leads sometimes it will show 0.1 is this a cause for concern? I get the impression that this should 100% zero it out
But then, why is my brand new Fluke 87-V still showing a residual reading on AC millivolt range, even with the leads shorted out ? And why some meters, like the 87-V, take soooo long to go down to zero after taking a measurement ? Thanks for any reply.
It is probably because of stray AC fields from wiring in the walls and stuff. When you short out the leads, the leads act like a "coil" and current is induced.
I have a fluke 83 multimeter that works with the back cover off when I put the cover back on even without the three screws sometimes the meter won't come on. It will show a random display on some of the dial settings but it always works properly with the back cover removed. I can't find any broken solder joints on the board. I cleaned the contacts for the buttons and the display contacts. But still can't put the meter back together because it will stop working with the cover on it.
I also just noticed If I remove the internal cover with the speaker on it I can install the back cover and everything works fine. Maybe it's the dial selector switch?
I have a Fluke multimeter that recently began showing a significant error when taking dc voltage measurements. It displays twice the actual voltage being measured. Have you come across that before? I’ve never had any issue with Flukes before.
ANY meter can fail over time. Just because a Fluke costs 2 to 5 times more than other Meters, does not mean it will last forever. If everything besides DC is working properly, it can probably be repaired easily. If other functions have problems, it may be time for a new meter.
@@MultiMeterChannel I have a Fluke that I thought was broken this afternoon... and the issue has me totally confused... I'm working on an antique gas tractor... 12v battery... the battery shows 12.3 volts engine off... Start the engine and it shows 20-40 volts... In fact if I just touch the ground lead from the meter to ground post on battery it shows the same without touching the positive lead to anything.... I found this while checking to see if newly installed alternator is charging... Took alternator and eventually the starter as well off the tractor... Only thing hooked up is ignition coil... Same thing.... 12.3 volts engine off... 20-40 engine running... Thought multimeter must be crapped... Tried it on two other tractors, normal.... Mind blown here
Ok so I have my positive lead connected to metal and my negative lead connected to nothing I'm getting a increasing mV reading its -233.9 mV and climbing, why is this?
+Shutter Eff3ct Yes, it is normal for a Clamp meter that measures DC current to not zero out when set to DC. But, it should still show zero when set to AC. If your Clamp meter meter is capable of measuring DC, it should have a button that will zero out the reading, before taking your measurement.
+Shutter Eff3ct Clamp meters that measure DC Amps use Hall effect sensors that can pick up stray magnetic fields, so the reading can vary based on the position of the meter. So, the manufacturer is suggesting that you clamp around the wire you want to measure, with the power off. Then once around the wire, zero out the meter, then turn power on and take the measurement. This will be the most accurate reading. If you zero out before clamping on the wire, the reading can change from moving the meter on to the wire.
@@MultiMeterChannel You wrote "Then once around the wire, zero out the meter, then turn power on and take the measurement." How can you zero out a meter before turning power on? Seems a bit counterintuitive. Thanks for your advice if any. Highly appreciated. 🙂
I know this is old, but my leads go from -26.9 mV to like 29 and up to 78 mV. this video said put them together that causes a "short" which makes it so that it grounds the multimeter and it should in theory level out?
If you short the leads together, you should not get the mV voltage fluctuations anymore, and the meter should be solidly at zero. If you still have fluctuations, you have a very poor quality meter, or it is damaged.
I check phase to phase voltage readings on Fluke DMM and it shows 20Vac. Then when I remove one of the lead from phase and place it in the air and other lead still on the phase, still the DMM shows 20Vac! Why is this?!
Rizwan Khan What voltage are you trying to read? Are you measuring the 120 volt phases on a panel in your house, or at an outlet somewhere? Are you sure your test leads are good? If you do a continuity test on your leads, do they pass? If your leads are good, you may just be seeing a ghost voltage.
My meter works at contionoty , resistances , current except voltage . when you turn it to voltage measurement it starts reading but when you connect the test leds to a battery it runs to 0.00 PLEASE I NEED YOUR HELP.
What if it only does it if you walk up to it and it stops when you walk away 🤔 every multi meter has done this to me since day one. I just recently was told it’s not supposed to do that
How high that reading goes will depend on the EMF field that is around it, the response time if the meter, and what range it is in. 200 mV for what I was demonstrating is normal for many meters.
Well I don't know about you but my multimeter is picking up 199 volts then goes back to zero and starts counting again so it must be screwed. Got to take it back. The irony is it works when a load is on it.
What is solution for😌 this problem. I bought fluke meter of ₹ 5,350 , when I got it I checked meter by putting in 230v socket in audible continuity mode 😒suddenly a long beep, increasing of digital value on board 😞 ,,, I thought meter has been gone 😖 I lose my money that has been saved from 1 year..... 😞😞 what is solution for😌 this problem... 🥺🥺
@@mohammedhassen2312 i am sorry to hear that partner.... note that the continuity function is not to be used on live circuits, keep that in mind and take a good look at the provided manual when you get a new meter to familiarize yourself with it and to avoid costly mistakes such as this one. please be safe and also NEVER rely on a multimeters safety features to provide immunity to shock and other related hazards, things happen when least expected!

Ive come to this video when trying to find out why my multimeter is showing a dc voltage, which gradually grows. and its not mV. It ranges between 1 and 4v
I tought my multimeters fuse is blown by measuring the high current by mistake. There are 2 terminals for COM and 10A. Sometime I forget to place the pin from COM to 10A.😂
after all these years I've never seen this problem until today, and you helped me not lose my mind trying to figure it out. Thank you!
Thank you for this I didn’t understand why it was doing that and thought my new multimeter was broke 😂
Amazing video. Titled well and I found this concise answer to my question in 1.5 minutes Thanks!
Thank you for making this video. I have several multimeters but avoid using my Fluke just because I find this ghost voltage really annoying.

Take it apart and touch all the solder joints up and it should work just fine

Thanks for saving my sanity. I was about to take a really big sledge hammer to my multimeter.
Damn. I was hoping for an answer to this question for when a multimeter actually shows voltage when not connected. Mine was showing 1-3V..
Why is my multimeter showing only the number (1)? When I need a 12v reading.
My multimeter shows 80 DCV whenever they're not touching something. It keeps reading my 12V car battery as having 20+ or even 30+ DCV.
Hi, what setting should I use to check voltage on my truck harness side connector. I want to find out if I’m getting 12v to my vsv connector.
Thank you for this video.
Is it supposed to be doing this even without leads plugged in? I have a DMSC683A. I bought it secondhand from a friend who went to UTI
Why do some not do this when new, but eventually start showing fluctuating voltage or ohm readings when first turned on?
Ok so I have my positive lead connected to metal and my negative lead connected to nothing I'm getting a increasing mV reading its -233.9 mV and climbing, why is this?
something like this?
ruclips.net/user/shortsDy-N1WPPqag
thanks for the simple explanation
How bout if its constantly showing negative volts? but they go back to 0 if both tips are shorted.
Thanks. I want to ask; is it normal to have 0.4 dc amp (range 40 A) when not using the clamp , shouldn't it be just zero ?
+Shutter Eff3ct
Yes, it is normal for a Clamp meter that measures DC current to not zero out when set to DC. But, it should still show zero when set to AC. If your Clamp meter meter is capable of measuring DC, it should have a button that will zero out the reading, before taking your measurement.

yes it has rel button. According to manual I should measure then zero it then re-measure.

You can find many on-line, at a site like Amazon. Or, at any home improvement store like Lowe’s or Home Depot
What should we do if voltage readings are shown(fluctuating readings) even when leads are shorted?
Ramees_skp
With the leads shorted, how much of a fluctuation are you seeing?
@@MultiMeterChannel Actually whichever option I take it is the same fluctuation.only the decimal point is changing

hi. I have a chauvin arnoux c.a 5220 multimeter that's show 0.23v dc when I put the probes together. I guess it's broke then?
When in continuity mode and both leads connected together, my multimeter reads 750. It should read 0, correct? What do you think the problem is?
