Influence of ambient
temperature Current and voltage: 0.013 %/°C (0.0072 %/°F) of nominal value
Power: 0.018 %/°C (0.01 %/°F) of measuring range
Error change due to variation
of an influence quantity in the
manner described in Section 6
of IEC 688:1992 2 x error allowed for the reference condition applied in the test. Error due to temperature variation
as above.
Error in measurement when a
measurand is within its
measuring range, but outside
its reference range 2 x error allowed at the end of the reference range adjacent to the section of the measuring range,
where the measurand is currently operating / being tested.
