temperatures. These three curves serve to determine the deviation of the
measuring instrument for specific field strength and temperature readings so
as to correct the field values displayed. So a measurement accuracy of
0.1% is achievable.
Each AS-active-probe have its own individual linearity curve. If an AS-probe
is replaced, the linearity curve have to be renewed too.
Examples of typical linearity curves can be found at our application note
PE003 – zero chamber.
The linearity curve serves as a test record.
The following illustration shows an exemplary set of linearity curves:
