Top scale is ohms. When measuring in the 250 VAC scale, top scale 10 would be about 65 volts... because you use the numbers down.
However the "zero" on your meter is off. With no probes connected, that needle should line up with the left side of the scale where the 0 are. Try to adjust your needle using that clear screw in the bottom center of the clear area.
OK... did you read that same on the left (between the two yellow arrows on my mark-up) as you did on the right, across the two screws on the right? With the breaker handles "on"? That sounds very unexpected, and would mean both breakers failed. Probably I should have labeled the screws in the picture differently. When you are measuring the two A screws, I am expecting one probe on one screw hooked to a white wire, and the other probe touching the other screw that is hooked to a white wire.
One bad breaker is a lot more likely than two.
While your meter may be a little off, you should have the same voltage on the top and bottom screws of a breaker (when on) as you have with the probes not touching anything: zero.
