multimeter is not working. When I switched on the multimeter , the multimeter is displaying the some battery symbol .After some time it gets switched off. I have attached the image. What will be the problem?
Have you tried replacing the battery?
Thanks @ helius for sparing us all a 1000 page troubleshoot and repair thread
Did it maintained the calibration after battery replacement?
The pictured multimeter is of a class that most likely never experienced any calibration.
Darwin Moment, like reading a troubleshooting guide for your new gadget and the first bullet is "Is it plugged in?" And you ask yourself "do they really need to ask that?". I guess so
ok, seems we won't have 1000 pages of troubleshooting but 1000 pages of flaming instead
Let's just celebrate a success and be happy it is fixed easily!

And then you do and the customer says it is. You drive an hour to find out they didn't bother to check and it really is unplugged, kicked by a foot. Resolution code: operator error
He should open it anyway and start poking around, what do we do if not?

Yep, problem solved, it is the beginners section.
The lesson to learn is good for any electronics troubleshooting: Is the power good? (Secondarily have you RTFM?)
Please don't use that meter for hazardous voltages i.e. anything above 60VDC or 30VAC! It's not safe.
The 10A current measurement is also unfused. Don't use it on anything not powered from a current limited power supply small battery (i.e. AA cells), otherwise it can catch fire if overloaded.
Really that multimeter is a turd. Ideally it should be replaced with a decent one, long term.

Actually, it probably have the ability to be calibrated.
It looks like a variation of the DT830B that I have. There is a VR on the board for the DT830B. I calibrated my pair of DT803B with my 5V reference from Voltage Standard. I held pretty well too.

Any meter can be calibrated. Just compare the displayed values to the expected values and write down the numbers on a piece of paper.
Note that calibration does not involve any adjustments of the displayed value.
This multimeter may have one or more potentiometers for adjustments, but I doubt anyone bothered with a thorough calibration.
It probably would have been cheaper to buy a new multimeter.

That meter, if it indeed like the DT830, would have just one (cheapo) VR. I would adjust that against the 5V standard I have.
While some would sneer at cheapies like DT830B, but it has its use. For $1-ish, it is rather decent for the money. It holds to the nominal 1%-2% accuracy rather nicely, some range better than others of course...
