Vertical sensitivity is 2mV/div: ±4%
(sampling or average value sampling mode);
Vertical sensitivity is 5mV/div~10V/div: ±3%
(sampling or average value sampling mode)
Vertical shift is zero and N>16: ±(5% x reading+0.1 grid+1mV)
and select 2mV/div; ±(3% x reading+0.1 grid+ 1mV) and select
Vertical shift is not zero, N>16:± [3% X (reading+vertical shift
reading)+ (5% x vertical shift reading)] +0. 2div) set from 5mV/div
to 200mV/div+2mV; set value >200mV / div to 5V/div+50mV.
Under identical setup and environmental conditions, the voltage
difference (rV) between two points of the waveform after the
average of ≥16 waveforms acquired waveforms is taken:
