When measuring using the auto-ranging function, only the following items are
changed.
Basic Setting Conditions (Status Settings screen)
Input-Module-Related Conditions (all channels)
Trigger Criteria (one channel only)
Setting Choice Auto Setup
Timebase* Auto setting value (x 1 time axis magnification)
If the input signal frequency is below 3 Hz, the timebase cannot be set automatically.
* Among the channels with waveforms enabled, if the measurement range of the lowest-
number channel is 5 mV/div (the highest sensitivity range), or if the difference between
the maximum and minimum value of the input signal is eight divisions or less, the time-
base is set according to the second lowest-numbered channel.
Setting Choice Auto Setup

Analog Trigger
(Only Level Trigger No. 1 can
be set. Others are all Off.)
Only the lowest-numbered channel is set.
(However, if the difference between the maximum and
minimum values of the input signal is eight divisions or
less, the trigger is set for the second-lowest-numbered
channel.)
[Expanded] setting, Trigger No. 1
Level Trigger, Slope:

Trigger Level: Auto setup value
Filter: Off
If the “Auto-ranging failed” warning message appears when you attempt
auto-ranging
This message is displayed when the range could not be determined from those
channels having waveforms set for display ([On]), and measurement is stopped.
Make the settings manually while verifying the input signal with the Level Monitor
(⇒ p. 116).
