Differential measurement
A differential measurement is a
measurement with two instruments
Measuring instrument (A) and Reference
instrument (B), measuring the angular
difference between the two. This means e.g.
if the angular change in both instruments is
the same the displayed value (Difference A -
B) does not change. In principle this is a
special relative measurement.
In the following measuring tasks the
differential measurement is especially used
•
Measurement on object with
vibrations imposed.
•
Measurements on unstable systems or objects
Example: Measuring the flatness of a machine bed. The reference instrument is placed
on a stable part of the machine where the measurement is not interfered. With
the measuring instrument the measurement is taking place without removing
the reference instrument.
Practical example
