CHAPTER 3 Settings and Measurement
When setting the XY position, a position reference line (pink line) indicating the position reference value is
displayed.
Position reference line
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
When the VERNIER is set to 100%, it becomes an equal magnification. Therefore the waveform display is
shrunk by the VERNIER setting magnification.
For example, when the VERNIER is set to 80%, it is displayed with a size of 80% compared with 100%.
(The above figure shows the sample when the XY position is set to 50%)
During VERNIER setting, a VERNIER reference line (green line) pointing to the VERNIER magnification is
displayed.
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%).
