A VOM only puts out current when it is measuring resistance. Since the circuit must be de-energized when measuring resistance, and you need a source of current in order to measure the voltage drop across the resistor, the VOM/VTVM/DVM/DMM provides it.
The amount of current used is miniscule, and it's highly unlikely you could cause damage with it, unless you're trying to measure continuity through your PC's chipsets. The battery used to power the multimeter is NOT passing that full voltage through the probes.
