Time axis range (time/div):
Value set automatically
(Magnification/compression ratio: x1
Sequential save: OFF
Trigger conditions (one channel only)
Trigger mode: AUTO
AND/OR for internal and external
triggers: OR
Pre-trigger: 20%
Internal trigger:
Enables only the waveform display
channel with the lowest number. (If
the difference between maximum and
minimum is 2 divisions or less, the
next channel is enabled.)
Trigger type : Level
Slope: rising
Trigger level: value set automatically
Filter: OFF
NOTE
When the auto-range function is engaged a trigger output signal
is generated. Take suitable precautions when using the auto-
range function concurrently with the trigger output connector.
4.6 Auto Range Function
This function automatically selects the time axis range,
voltage axis and zero position (excluding when the setting
of input coupling is "CLAMP").
The time axis range is applied to the lowest numbered
channel with waveform display enabled, and is
automatically set to record 1 to 2.5 cycles on the Waveform
Screen.
Procedure
Waveform Screen
1. Press the
DISP
button to display the Waveform Screen.
2. Press both sides of the
TIME/DIV
button for at least 2
seconds to activate auto-ranging.
3. Press the
START
button to execute, or press the
STOP
button
to cancel. To cancel forcibly during auto-range operation,
