9.1 Accuracy
Specified accuracy is valid after a 10 minute warm up period in temperature of 23 ± 5 °C.
Uncertainties include long-term stability, temperature coefficient, linearity, load and line regulation and
traceability of factory to national calibration standards.
Accuracies are assigned in % of the set value.
The Specified accuracy is valid for one-year.
