Spin the rotary switch a few times, it might be oxide on the switch.

I don't have this meter, but maybe take it apart and look for any obvious signs of problems?  Bad soldering, some debris inside?

I suspect the cost of returning this meter to whereever, unless locally, you bought it will be more than the cost of the meter?

it wont beep if it's over 50ohms.

put a wire between the sockets incase the leads are bad.

You mean you've literally changed em, or only switched their positions? Just wanna verify I got it right (as your English isn't the greatest)
Anyhow, provided you did try different probes, I'd say it's either a faulty buzzer, a bad solder joint, or a faulty component.
You'd have to open it up and have a good inspection (and possibly some testing with another DMM) to get more insight.

well the buzzer should beep when you turn it on or switch ranges/modes
so that's easy to test.  :)

Maybe the internal fuse is wacked out,

I fixed a similar cheapie meter the other day that has shared 200ma current and V  \$\Omega\$  socket

The fuse looked ok but failed on the test

The fuses are the 2 components at the bottom of the board labeled F1 and F2.

Have you Re-solder the connector sockets and joints?
Flimsy board can't take mechanical stresses.

My money is on the 600ma fuse on the left gone zapski...

If it is blown, where is OP SpyTattoo going to get one of those halfassed circus sideshow midget fuses with the correct value of 600ma?  :-//

What were they smoking at the ANENG design (save money) meeting for this meter?   :palm:

Hi, remember to plug in both the probes into the sockets when you solder so that the rings will stay concentric when you solder the joints. Hope you understand what I mean.

It is not blown. I remove fuse and wire jumper directly not solve problem.

Is it another problem?

Do you have a schematics for this meter? Thanks
