[1] Add 20 counts in dual display ac over dc, dc over ac or ac+dc.
[2] AC+DC ranges are specified from 2 % to 140 % of range, except 1000 V is specified from 2 % to 100 % of range.
[3] When using the relative mode (REL Q) to compensate for offsets.
[4] Add 4 counts/10 mV AC in dual display ac over dc, dc over ac or ac + dc
[5] Add 10 counts/100 mV AC in dual display ac over dc, dc over ac or ac + dc.
