When vertical sensitivity is 2mV/div, 5mV/div: ±4% (sample or average
sampling mode);
When vertical sensitivity is 10mV/div~5V/div: ±3% (sample or average
sampling mode).
When vertical position is zero and N ≥16:
± (4% x reading + 0.1 div + 1mV) and 2mV/div or 5mV/div is selected;
± (3% x reading + 0.1 div + 1mV) and 10mV/div~ 5V/div is selected.
When vertical position is not zero and N ≥16:
± (3% x(reading + vertical shift reading) + (1% x vertical shift reading)] +
0.2div). Set from 2mV/div to 200mV/div plus 2mV;
Setup value > 200mV/div to 5V/div plus 50mV.
Under identical setup and environmental conditions, the voltage
difference (
V) between two points of the waveform after the average of
≥16 waveforms acquired waveforms is taken: ± (3% x reading + 0.05 div)
