1500 mT 1.02
2000 mT 1.03
The frequency response factor and shape factor are multiplied with the basic accu-
racy in dependence of the respective measuring parameters, and then added to the
basic accuracy.
Example:
Measuring
B
eff
= 1000 mT at a frequency of 5 kHz.
The basic accuracy is 0.5%. The frequency response factor is 0.9%. The shape factor
is 1.02.
The error from of these factors is 0.95 * 1.02 = 0.97 = -3%
For the measurement you have to calculate a total error of -3%±0.5%.
