Model UT71A/B: OPERATING MANUAL
Remarks:

Display:
a) True rms are valid from 10% of range to 100% of range
b) AC crest factor can be up to 3.0.
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.
At 10A range:
a) When the measured current is 5A, continuous measurement is allowed.
b) When the measured current is between 5A-10A, continuous measurement 10 seconds and interval more
than 15 minutes.
