Help ! voltage is only 0.3 v from receptacle

Recently I renovated my kitchen. When I tested a hot & neutral wires using a digital multimeter in the kitchen, the voltage is only 0.3v. Then I connected a receptacle to that hot & neutral wires, tested again, still got 0.3v from the receptacle holes.

I tried to use that receptacle to power up a table lamps, and it works fine. I know this receptacle worked before the renovation, it used to provide power for a refrigerator.

The multimeter is in good condition and I tested already.

Is there anything I should worry about ? or just leave it like that?

Thanks for any advice...

What are you reading when you touch the white and black wire? Should be 110 volts.
Tried plugging something in that uses more power like a drill?
Tried a different outlet in a different room to test the meter?

Mod Note: No, not 110 volts. It should be about 120 volts.

A poor or marginal connection can influence the voltage readings.

Sometimes the probe just won't pick up a reading from the slots. If it is a digital multimeter the 0.3v is probably just induced voltage.

Are you certain the meter is in AC mode and not DC mode ?
If yes.... put meter into OHMS mode and touch the two leads together. Your meter should register the short.... if not you have a defective probe or a blown meter protection fuse.

It's my fault. One of the test lead wasn't pushed into the tester completely. I think that's why sometimes it get wrong readings.

Thanks for everybody's help !!!
