80 Measuring Signals With the Auto-range Setting

Measuring Signals With the Auto-range Setting

• Be careful when performing auto-range measurement while using the TRIG OUT signals. Starting

a measurement with the auto-range setting outputs a trigger signal from the TRIG.OUT terminal.

• Input signals (waveforms) before starting a measurement with the auto-range setting. The auto-

range function changes the setting depending on a signal inputted on the start of execution.

• When an input signal acquired across the channel lowest-numbered among the channels with

the [Display] button set to [On] has an extremely small level, the sampling rate is specied

depending on the input signal of the next lowest-numbered channel.

• If the range setting fails for every channel with the [Display] button set to [On], the instrument

displays a warning message and cancels the measurement.

• When the auto-save is set to on, the instrument saves the data after specifying the setting value

of the auto-range.

• The instrument cannot choose an adequate automatic range for a signal with a frequency of

lower than 10 Hz. Manually choose a measurement range.

• The auto-range function is not available for the following modules:

Model 8967 Temp Unit

Model U8969 Strain Unit

Model 8970 Freq Unit

Model MR8990 Digital Voltmeter Unit

Model U8991 Digital Voltmeter Unit

Model 8973 Logic Unit

Analysis Method

4.1 Reading Measured Values (Trace Cursors)

You can read measured values (scaled values when the scaling is used) using trace cursors on the

waveform screen. The instrument can simultaneously display up to eight trace cursors. You can

read differences in times and measured values between any two cursors you choose from among

all cursors.

For information about other types of cursors than the trace cursor, refer to “2 Operating the

Waveform Screen and Analyzing Data” in Instruction Manual.

Set [CH Info] toggle switch to [On].

Click [CH Info] toggle switch to switch between [On] and [Off] for the information display setting of each

channel.

Click [Trace cursor].

Choose one or more cursors to be displayed from among

[Trace cursor A]

through

[Trace

cursor H]

by tapping them.

The chosen trace cursors are displayed on the waveform screen.

Drag the trace cursors on the waveform screen to move them.
