Notes for AC + DC voltage specifications:
1 Input impedance: Refer to Ta b l e 7 - 1 7 .
2 These specifications are defined for signal input > 5% of range.
3 Additional error to be added for frequency > 15 kHz and signal input < 10% of range: 3 counts of LSD per kHz.
4 2% over-range on all ranges except AC 1000V.
