• True RMS are valid from 10% of range to 100% of range
• AC crest factor can be up to 3.0 except 1000V where it is 1.5.
• A residual reading of 80 digits with test leads shorted, will not affect stated
accuracy.
• When frequency is lower than 100kHz, the accuracy guarantee range 10%-100%.
• When making AC+DC measurement, the accuracy need to add (1%+ 35 digits) of
reading based on the above table.

• When the measured current is ≤5A, continuous measurement is allowed.
• When the measured current is between 5A-10A, continuous measurement must
be ≤10 seconds and interval more than 15 minutes.
