Accuracy
Specified accuracy is valid after 10 minutes warm up in temperature range 23 ± 3
C.
Uncertainties include long-term stability, temperature coefficient, linearity, load and line regulation
and traceability of factory to National calibration standards. Accuracies assigned in % are related to
the set value. Specified accuracy is one-year accuracy.
