5-4

Accuracy, Average

Acquisition Mode

±(DC Gain Accuracy× reading+0.1div+1mV)

Average of ≥16 Waveforms with vertical position not at zero:

±[DC Gain Accuracy× (reading+vertical position)+(1% of

vertical position) + 0.2div]

Add 2mV for settings from 2mV/div to 245 mV/div

Add 50mV for settings from 250mV/div to 10V/div
