Remarks:
- Overload Protection: 1000V.
- Display:
a) True rms are valid from 10% of range to 100% of range
b) AC crest factor can be up to 3.0 except 1000V where it is 1.5.
c) A residual reading of 80 digits with test leads shorted, will not affect stated accuracy.
d) When frequency is lower than 100kHz, the accuracy guarantee range 10%-100%.
e) When making AC+DC measurment, the accuray need to add (1%+ 35 digits) of reading
based on the above table.
