Multi-point scaling
With ZW-8000@, measurements are taken at multiple locations and a precision stage is used to minimize the
measurement error between the measurement value and the actual distance.
This function is enabled when nonlinearity occurs in the measurement error of the measurement value and the
actual distance.
This function cannot be used with ZW-7000@/ZW-5000@.
Example: When correcting measurement values to match actual distances at 4 points

Important
Separate each distance between the N specified points by at least 1% of the rated measuring range for the connected
Sensor Head.
For example, for the ZW-S8010, the two measured points must be separated by at least 1 mm × 0.01 = 0.01 mm as
the measuring range is 1 mm (± 0.5 mm).
