Additional specifications for AC functions:
The measuring value is gained and indicated as effective value (True RMS, AC
coupling). In case of non-sinusoidal curves, the indicating value becomes inac-
curate. Thus, an additional error occurs for the following crest factors:
crest factor from 1.0 to 2.0 additional error + 3.0 %
crest factor from 2.0 to 2.5 additional error + 5.0 %
crest factor from 2.5 to 3.0 additional error + 7.0 %
Maximum crest factor of the measuring signal:
crest faktor 3.0 @ 3000 digits
crest faktor 2.0 @ 4500 digits
crest faktor 1.5 @ 6000 digits
Measured values < 20 digits are set to 0 on the digital display
