The VOM has the higher loading effect, because it has a lower impedance. It is typical for a VOM to have an impedance of 20K ohms per volt while the DMM has a fixed impedance of 10M ohms or 20M ohms.

First of all, DMM stands for Digital Multimeter. The -multi implies the meter measures several different parameters, usually voltage, current, resistance, and sometimes other things such as frequency. The input characteristics of a DMM will be very different depending on the parameter selected. For current, the ideal meter would have zero input resistance. Since the ammeter is inserted in series with the circuit under test, any resistance will alter the measured current, introducing error in the measurement.
You can use the DMM to test continuity in the cable.
Yes. There is a sign of Speaker/sound on a side DMM. Move the knob of DMM on that symbol. Now connect one prob of the DMM on one circuit element & one under that(If you are designing the circuit on PCB or plain board). If a sound come out of that then it means that your circuit element & the portion below that are properly connected.

Electricians use a clamp or clamp-on ammeter to measure current. The handles are squeezed together and the "jaws" open up. The clamp is then slipped over the conductor and the handles are released. The "jaws" close around the conductor and the meter is then in a position to measure current in that conductor. When current flows in a conductor, the current generates a magnetic field around the conductor. And the clamp-on ammeter can "feel" the current and measure it, thus permitting an investigator to know how much current is flowing in that conductor. The clamp-on ammeter is a stand-alone meter, but can sometimes be the kind that is plugged into a digital multimeter (DMM). A link to the Wikipedia article on the clamp ammeter is provided.
