No it does not check continuity, neither if the electricity is on or off.
Your question indicates that you are putting your health and possibly your life at risk working on house wiring. Open neutral means that between the wide slot of a grounded receptacle and the neutral bus of the breaker panel, the white wire isn't connected. Shut off the house power. Look at the the screws and check the copper of the white wire(s) is tightly held under those screws. Check the receptacle to cracks. See if the wires all look like they have good plastic insulation all the way to under the screw heads. If the receptacle is discolored or cracked, the screws pitted or discolored, replace the receptacle. If the receptacle, the connection and the wires look good, the break is somewhere else. Without proper tools and experience you could spend days trying to find what a competent electrician could find in an hour.
