the operation mentioned above
UTD1000L Series is designed with autoset
function that can automatically adjust the vertical
scale, scan timebase and trigger mode based o

obtained. To apply the autoset function, the tested
signal should have a frequency at 20Hz and
duty cycle 1

the channel is closely connected to DC autoset
When DC autset is set to off all signals in the
channel is AC coupled If DC autoset is on, the
channel will choose the current setting as coupling
mode, when the current setting is DC coupling, the
signal will be DC-coupled and vice versa
.
For example:
1. Input 1kHz 2Vpp sine signal into two
channels set coupling mode for both channels
to DC press Shift+UTILITY and then F3 to set
