Um	Unit of measurement.
Min value	Minimum value in the record set.
Max value	Maximum value in the record set.
Cur value	Current value of the variable.
v/div	Number of engineering units that are represented by a unit of the y-axis (i.e. the space between two ticks on the vertical axis).
V Blue cursor	Value of the variable at the intersection with the line identified by the vertical blue cursor.
V Red cursor	Value of the variable at the intersection with the line identified by the vertical red cursor.
H Blue cursor	Value of the variable at the intersection with the line identified by the horizontal blue cursor.
