Maximum Operating Error
Operating error (B) is an error obtained within the rated operating
conditions, and calculated with the intrinsic error (A), which is an error of
the instrument used, and the error (Ei) due to variations.
A
: Intrinsic error
E
1
: Variation due to changing the position
E
2
: Variation due to changing the supply voltage
E
3
: Variation due to changing the temperature
E
4
: Variation due to series interference voltage
E
5
: Variation due to resistance of the probes and auxiliary earth
electrode resistance
E
7
: Variation due to changing the system frequency
E
8
: Variation due to changing the system voltage
