ELECTRICAL SPECIFICATIONS FOR U1213A
Accuracy is given as ± % of reading +
no. of least signifi cant digits at 23 °C ±
5 °C, with relative humidity Less than
80% R.H.
AC voltage, AC current, AC+DC
voltage, AC+DC current specifi cations
are ac coupled, true R.M.S. and are
valid from 5 % of range to 100 % of
range. The crest factor may be up to
3.0 at full-scale except the 1000 V
and 1000 A ranges where these are
1.5 at full scale. For non-sinusoidal
waveforms, add (2 % reading + 2 %
full scale) typical, for crest factors
up to 3.
