ii. Under Scope mode

The specification is same as Hi. Under Multimeter mode, press RANGE button to toggle between

frequency and duty cycle mode.

On the top right corner of the display shows the waveform’s RMS value, for reference only. When the LCD

displays 1-10 period waveform cycle or the peak-peak difference value is greater than 1/3 div, the reading is

valid, otherwise the Meter displays “ ————“
