(Internal limit processing with ± 10% FS.) The full scale in the bipolar input setting considers plus and minus separately. For example, in the case of ± 10V input, limit processing is performed up to ±11 V. (20 V is not treated as FS.) Similarly, the accuracy with ±10 V input is also specified as one-sided FS treatment, and the accuracy is calculated as 5 mV (0.05%) ± 1 digit.
