Span, Position and Trace Functions to Adjust the Waveform Display
1. Starting data capture
Trigger functions can be used to control the timing of the start of a recording,
and the timing of the end of a recording.
The span, position and trace operations can be performed while the GL240 is in
the Free Running mode, while it is recording data, replaying data.
The changes are applied to the displayed data only, and this change dose not
affect the recorded data.
1. How to change the Span setting
The Span parameter is used to adjust the amplitude of the input waveform.
This setting is made in the Free Running mode.
(1) Set the displayed span for CH 2 to 100°C.
(2) Push the [SPAN/POSI/TRACE] key to select the SPAN mode.
(3) Use the
and
keys to make CH 2 active (display enlarges on the
selected channel).
(4) Use the
and
keys to change the Span value. Here the value for
span is set to 100°C.
When this setting is changed, the waveform screen scale will be set to
"+100.0°C to +0.0°C".
2. How to change the Position setting

set by the upper and lower values.

(2) Use the
and
keys to make CH 2 active (display enlarges on the
selected channel).
(3) Use the
and
keys to set the Position value to "+80.0°C to -20.0°C".
When this setting is changed, the waveform screen scale will be set to
"+80.0°C to -20.0°C".
3. How to change the Trace setting.
The Trace parameter can be used to specify the selected waveform to be
visible or invisible on the display.
(1) Push the [SPAN/POSI/TRACE] key to select the TRACE mode.
(2) Use the
and
keys to make CH 1 active.
(3) Use the
