Remarks:
 When ≤ 5A: Continuous measurement is allowed.
 When > 5A: Continuous measurement for less than 10 seconds with intervals of
more than 15 minutes between measurements.
 True RMS is applicable from 10% of range to 100% of range.
 AC crest factor can be up to 3.0 except 1000V (DC) where it is 1.5.
 A residual reading of 10 digits with test leads shorted, will not affect stated
accuracy.
