CHAPTER 3 Settings and Measurement
Span
Span can be selected when Span mode CH is set on X-axis and Y-axis.
This is a common setting with Span set in Y-T waveform display (AMP menu).
Changing the Span setting affects the position reference point and the basic range of the vernier (the range
displayed in the graph when the vernier is set to 100%)
For details of the Range mode/Span mode, refer to "3.3 Operation Modes"-"(3) XY waveform display"-"
Range mode/Span mode".
Zero point
Automatic zero adjustment is performed.
Automatic zero adjustment for 2CH of the analog CH set on the X-axis and Y-axis is performed.
When the analog CH input is set to temperature, automatic zero adjustment is not performed.
For details of automatic zero point adjustment, refer to "3.5 Setting Menues" - "(1) AMP settings" - "Zero
adjustmentfunction"
Referring to "3.5 Setting Menus" – "(1) AMP Menu" – "Automatic zero adjustment" – "Zero adjustment reset",
please reset for each analog CH.
Origin
Set the origin of the X-Y graph.
Center and lower points left can be selected.
When "Execute" is selected, the XY position is initialized to the position selected as the origin.
• Initialization position
Center: X-axis position 50%, Y-axis position 50%
Lower left : X-axis position 0%, Y-axis position 0%
Center: Origin Origin: Lower left
Waveform clears at the start of recording
Set whether to erase the XY waveform display (pen trajectory) at the start of capturing.
When set to On, the XY waveform display is erased at the start of recording.
XY display clear
Manually erase the XY waveform display (pen trajectory).
The erased waveforms cannot be restored, hence save the screen copy from the FILE menu if necessary.
For details of XY display clear, refer to "3.5 Setting Menus" - "(7) FILE menu" - "Screen copy".
