[1] AC conversions are ac coupled, true rms responding, and valid from 3 % to 100 % of range, except 400 mA range (5 % to 100 %
of range) and 10 A range (15 % to 100 % or range).
[2] The Meter is a true rms responding meter. When the input leads are shorted together in the ac functions, the Meter may display a
residual reading between 1 and 30 counts. A 30 count residual reading will cause only a 2 digit change for readings over 3 % of
range. Using REL to offset this reading may produce a much larger constant error in later measurements
