Difference between continuous and point by point modes?

What is the difference between continuous and point by point modes of data acquisition?

When using a VSM in Point by Point Mode, the measurement software sets the field for the desired point, allows the system to settle, then measures the moment under the constant field value. In contrast, when operating in Continuous Mode, the software sweeps the field and measures the moment as the field continuously changes. In this acquisition mode, VSM sensitivity is fixed. A continuous measurement is a very fast mode of acquisition but less precise than point by point acquisition.
