Multimeter continuous beeping in continuity mode

Block Image

continuous beeping even with test leads removed.

checked battery and opened it up with no showing of corrosion or something shorting anything. Fuse still intact also did not work with high voltages.

Was checking some dead phone batteries at the time and when got back to it it kept beeping.

does not want to work in any other mode at all.

What type of model and make of Multimeter do you have?

por

It just says Digital Multimeter DT369.

It isn't the clamp model I found when looking for a service model though.

por

added pic of Multimeter if that helps.

Hmm. That's one of those economical run-of-the-mill (but nonetheless useful, when they work) chinese meters. Well, you're going to have to buy a new one anyway if you'd want to troubleshoot this one ;)

I would have to agree with Flying Dutchman it's not worth putting any money in or time since you can buy a new for less but I strongly recommend fluke meters if you can they are roughed reliable and accurate. It sounds to me that the logic board is bad and needs to be replaced.

I was looking for a somple solution to my problem since I could not find anything conclusive online. For basic troubleshooting it was handy and one not to just throw stuff out I would always look for some solution as so the same problem doesn't resurface.

Just hoped this one would last longer since it had the few extras I needed.

Much thanks.

I understand, if you want I know sometimes I've had issues with other multimeters and a cheap and inexpensive way to troubleshoot is to replace the leads. It could be some bad leads that could be giving this problem.

por

it even beeps without leads. The guy at store said this the best they have and only other was a few cheaper ones.

Now, I know I'm very late and I understand that mine was working on all other modes, but here - I was using my cheap Chinese multimeter to measure voltage on an AC circuit a year ago, I was testing the continuity too like I was alternating between the two tests, at one point I mistakenly/ accidently tried to check the voltage in the circuit on the continuity mode, and then the beeping won't stop, well I was almost headed to the store to get a new one but then the beeping stopped, I checked if the multimeter was working on other modes, it was, surprisingly it was also checking the continuity but it wouldn't stop beeping, so I just tried to fix it somehow by doing deliberately making the same accident happen again and this time, it used to continue beeping but the buzzer would shut off in 20 secs or so, I then opened it up, removed the battery and placed it back in, and it started working on every mode like nothing had ever happened to it !

Gee, when this happens the feeling is a mixture of frustration and joy!

@cois Is there still functionality when reading the meter is it just the continuity .Is there continuity functionality , what reading are you getting with the leads not connected and connected, if all other functions are OK don't throw the baby out with the bath water. I agree with Flying Dutchman in that you need a multi meter to test this one . I have a drawer full of cheap multi meters (family seems to think its a good fathers day gift)and I use them all I have an expensive Snap on multi meter and I tend to use the cheap ones more often.

it just shows zeros no matter to what I turn it and of course beeps in continuity mode even with leads removed.

Picking up a very cheap model today just to be able to troubleshoot some minor things. and if there is something to fix here that would be great too.

I will be investing in a multimeter in the not so near future since where I live now the only way to get quality is to ship it. Got this one because it had the thermometer function which I needed.

I have a cheap Chinese multimeter UNI-T 132b and while I was unknowingly measuring currents way above 200 mA (the chosen scale) it just stopped measuring anything. The other functions worked like charm except DC small currents and diode/continuity. Similar to your situation, leads or not it kept on beeping while testing for continuity. Opened it up and found that the fuse for that circuit was gone. I temporarily 'replaced' it with some plain wire to test the multimeter for further damages. Beeping stopped and DC small currents measurement worked just fine. So that's like an error beep or something. Bought a new fuse for under a dollar and my multimeter is as good as new now. Hope you have the same luck!

I had the same problem with UNI-T 132E and the cause was a blown 500ma fuse. Easy fix :)

Ya Their is a video on youtube to solve this problem.

But HereIn my meter their is no fusees in their !

Don,t what to do !

I have an expensive Sumo DT-61 and it is having the same problem especially after i accidentally tested a charged 400 volts capacitor for dc voltage output of an electric mosquito bat/zapper which created a spark onto the lead probe but despite that all other tests are still working except for diode test, continuity test with never ending long beeping sound and ohm mode. My multimeter can accept up to 600 volts max for dc voltage test so I don't know why it is causing this issue. The fuses are also working and I had also changed the battery. I don't know if this is a chinese multimeter but I think that Sumo Industrial is either a british or scottish company based in Glasgow, UK and this multimeter is the most expensive one in the store since it is also an environmental multimeter that can measure noise, temperature, electromagnetic frequency and light. I think that I better RMA it.

check the fuse inside.....315mA 250V (5mm x 20mm)

less than $1

I hate it for you buddy, but I thinks it’s gone. Like you, I'm not sure what is causing it to continously indicate continuity regardless of the leads even being connected or not. I think I know what caused it in the forst place though. I probably monmentarily connected to a circuit intending to measure for voltage but failed to adjust the DMM measurement settings from ohlms to voltage. It's an easy mistake to make. I have always heard that it is one of the worst things you can do to one. I must have been fresh out of luck this time. My advise to you is not what you would like to hear. Don't waist your time and money and hopes on trying your troubleshooting skills on a possible fix. If you somehow did happen to isolate the problem, attempting a fix is ultimatly going to result in failure. That sounds a bit pessimistic but, really, it's not if your goal is to minimize the negative impact of accidently frying your only DMM. Seriously though, I screwed around with mine for almost a half an hour to no avail. In that time, I basicly only was able to check out the fuses. This turned out to be just pointless and I might have realized it earlier on if only I had looked at what had happened more logically instead of mourning my lose with false hope. It’s clear that the fuses were going to be intact. The beep indicates continuity. The DMM will not indicate continuity if this fuse is open. Remove the fuse. The beeping stops, but you definatly don't have the ability to measure continuity now though. More than likely you aren't going to be able to read resistance in ohlms either. Mine reads dead short with or without leads . More than likely all the readings are going to be comptomised. I wouldn't use it for anything critical. I wouldn't just chuck it though. It could still be useful to you. Clearly lable it as defective. That way you don't accedentally continue to use it, especally if you replace it with an identical unit. Blown DMMs are a right of passage in this trade. I promise, if you continue to delve into all things elrctronic, this will not be the last time you accidentally smoke your valued testing equipment. Being tired or over worked or trying to rush will cause you to make mistakes. Always try to work with a major emphasis on safety first and alot of useless misfortune can be avoided.

Might be something simple as an smd switching diode, 1 penny part. You require a certain amount of electronics know how to troubleshoot a circuit so if you dont know what an smd component is (and you probably dont if you have no other dmm) then put it on the shelf until you become more adept at circuit troubleshooting.

I have about 300 multimeters last count but hey thats my forte
