CHAPTER 3 Settings and Measurement
When setting the XY position, a position reference line (pink line) indicating the position reference value is
displayed.

VERNIER
The VERNIER is a function to adjust the amplitude (gain).
Adjust the display width range of the waveform displayed on the XY graph.
-10DIV -5DIV
10DIV
Reference point 5DIV 10DIV
Position 100%
Position 80%
Position 60%
Position 50%
Position 40%
When the VERNIER is set to 100%, it becomes an equal magnication. Therefore the waveform display is
shrunk by the VERNIER setting magnication.
For example, when the VERNIER is set to 80%, it is displayed with a size of 80% compared with 100%.
(The above gure shows the sample when the XY position is set to 50%)
During VERNIER setting, a VERNIER reference line (green line) pointing to the VERNIER magnication is
displayed.

VERNIER reference line
The VERNIER reference line is displayed at the position of 5DIV from the position reference point when the
VERNIER is set to 100%. When the VERNIER is set to 80%, it is displayed at the position of 4DIV from the
position reference line (80% position compared with 100%).
