Electrical Specifications for U1213A
Accuracy is given as ± (% of reading + number of least significant digits) at 23 °C ± 5 °C, with relative humidity less than 80 % R.H.
AC voltage, AC current, AC+DC voltage, AC+DC current specifications 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.
