● 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 (En) due to variations.
B=±(│A│+1.15
A: Intrinsic error
E
: Variation due to changing the supply voltage
2
E
: Variation due to changing the temperature
3
E
: Variation due to series interference voltage
4
E
: Variation due to resistance of the probes and
5
auxiliary earth electrode resistance
