Auto-setup
AUTO-SETUP FUNCTION
The auto-setup function is ideally suited for
quick measurements as no manual setup has
to be made.
Use the auto-setup function when the
screen no longer displays a signal after the
manual setup.
Autorange on (Fig. 44) :
•
Time/div and Volt/div settings are displayed
inverted.
•
The time base and input sensitivity are auto-
matically set for optimal viewing of the input
signal.
•
Auto-triggering is set for time base 0,2µs/div
or slower.
•
The slowest possible time base is 5ms/div.
•
The fastest possible timebase is 0,2µs/div.
•
The Y-position and trigger level are centered
on the display.
Autorange off (Fig. 45) :
•
Time/div and Volt/div settings are displayed in
a normal font (not inverted)
•
Cursor keys are used for changing the time
base and input sensitivity.

Note:
Changing the time base, input sensitivity, Y-pos
or trigger mode turns off the auto range-mode.
