Notes for U1272A AC+DC voltage specifications:
1 Overload protection: 1000 Vrms. For millivolt measurements, 1000 Vrms for short circuits with <0.3 A current.
2 Input impedance: 10 MΩ (nominal) in parallel with <100 pF.
3 For 20 kHz to 100 kHz accuracy: Three counts of the LSD per kHz of additional error is to be added for frequencies >20 kHz
and signal inputs <10% of range.
