Note:
1) In order to avoid errors or an unstable readout, the measuring circuits be shielded or at least twisted.
2) To set the basic range, first remove the safety cover over the pin connector at the rear of the instrument. "Ib set the basic
range and decimal point, plug in jumpers according to the assignment table. A zero shift is possible up to 25 % of the
full-scale range.
