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.
