It is possible to add a buzzer, all you need is a buzzer and a switch. This PCB lacks buzzer by design, and there are no leads prepared to just solder one in. If you just solder a buzzer, it will alter your other measurements. Instead just solder it with a switch to turn on buzzer in the diode test mode, and turn it off in the other modes.
And don't be like Michel Winslow it's a buzzer job ;)

I do not think there is an easy way to modify this meter, for to add a buzzer that sounds in the event of continuity,

between the two probes.

The easiest work around I can think of, is to just put the meter in its lowest scale resistance measuring mode, which is 200 ohms full scale. Then read what the meter says, using your eyes. If it is less than 10 ohms, then call that "continuity." Or whatever your threshold is for resistance low enough to call, "continuity."

You could even vocalize the BEEEEEP noise yourself, kind of like that guy who made all those weird noises in the old Police Academy movies.

Also you could just buy the kind of meter that does come with the functions you want, but you know, that might cost more.

Why would you need a buzzer?
The only reason for having one would be to test for continuity without looking at the display.
And usually that buzz you miss then happens in the diode testing mode on these cheap toys.
