Auto Setup (Auto Setup)
The auto setup feature automatically sets the SCALE (vertical axis), TIME/DIV (horizontal axis), trigger level,
and other settings to values that are most suitable for the input signals. This feature is useful when you are not
sure what type of signal will be applied to the DL850E/DL850EV. The auto setup feature will not work properly on
some input signals. There are some modules with which the auto setup feature cannot be used.
Center Position after the Execution of Auto Setup
The center position after you execute auto setup will be 0 V.

Waveforms that were displayed before you execute auto setup will be cleared.
Signals That Auto Setup Can Be Applied To
You can use auto setup for the following types of input signals.
• When module 720210 is installed: Simple, repeating signals with frequencies between 50 Hz and 10 MHz
When module 720210 is not installed: Simple, repeating signals with frequencies between 50 Hz and 1 MHz
• Signals whose maximum absolute input voltage is 20 mV at 1:1 probe attenuation to the maximum range × 10
The auto setup feature may not work properly for signals that include a DC component or high-frequency
components.
Undoing Auto Setup (Undo)
You can revert to the settings that were used immediately before you executed auto setup.
Initializing Settings (Initialize)
You can reset the DL850E/DL850EV settings to their factory default values. This feature is useful when you want
to cancel all the settings that you have entered or when you want to redo measurement from scratch. Default
reset refers to the act of resetting the DL850E/DL850EV settings to their factory default values.
Items That Cannot Be Reset

Undoing Default Reset (Undo)
If you perform default reset by mistake, you can undo it by pressing the Undo soft key.
To Reset All Settings to Their Default Values
While holding down the RESET key, turn the power switch on. All settings except the date and time settings (display
on/off setting will be reset) and the setup data stored in internal memory will be reset to their factory default
values. If you reset the settings using this method, the changes cannot be undone.
