Mulitmeter display not working - need info

I have a Craftsman 82028 digital multimeter with an odd problem.

When I measure anything, the bar graph works fine but the numerical readout never says anything but 0L (or .0L, 0.L, etc. so it does look like the auto-ranging feature is working).

For example, if I measure a AA battery, the bar graph shows 15 but the numerical display reads .0L

It's always been like this, but now I'm doing some diagnostics where I really need the numerical value to work.

Am I doing something wrong, or is this thing screwed up?

If the latter, is there any way to fix it, or do I just have to toss it and buy another one?

Not sure if craftsman warranties the DMM like it does hand tools. But it's worth a try.
Do you have the ability to select settings over auto ranging? Like the AA battery should be 1.2-1.4V not 15

If it's like this one you may be out of luck.

Your mulitmeter is actually working fine. Your range on the digital read out is smaller than your graphs. That 15 is probably supposed to be reading 1.5 you just have the range off....the "OL" message means the DMM is reading infinity because it is beyond its range_max.

Try this.....if using the auto range funtion; press mode until you are measuring DCV or it may look like Vdc and then make sure there is only the 10s digit read after decimal point. IF, the DMM is a knob you turn, turn the knob to DCV or Vdc section and set at 20.

Let me know if this solves the problem!
