•
∆
X: The difference between the X-axis values of and cursor x
• D+: Date and time at the position
Indicates the date and time (year/month/date hour:minute:second) of
measurement.
• Dx: Date and time at the cursor x position
Indicates the date and time (year/month/date hour:minute:second) of
measurement.
