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.
z 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.
