1.
Below 10 % of range, add 12 counts.
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.
3.
Frequency range: 1 kHz to 2.5 kHz.
4.
A residual reading of up to 13 digits with leads shorted, will not affect stated accuracy above 3 % of range.
5.
Specification increases from -1% at 200 Hz to -6% at 440 Hz when filter is in use.
