Ac Specifications; Table 7-10 U1212A Ac Accuracy ± (% Of Reading + Number Of Lsd) - Agilent Technologies U1211A User's Manual And Service Manual

AC specifications

The AC voltage and AC current specifications are true RMS AC coupled,
valid from 5% to 100% of range. The crest factor may be up to 3 at full
scale, except for the 1000 V and 1000 A ranges which is 1.5 at full scale.
For non- sinusoidal waveforms with crest factor ≤ 3, add 2% reading + 2%
full scale typical.
