The available units include "Source" and "Percent(%)". 
➢  Source: measures the amplitude at Y Cursor (taking the channel 
ground point as the reference). The measurement results include AY, 
BY, and △Y (its unit is consistent with that of the current source). 
➢  Percent(%): measures ratio at Y Cursor. The measurement results 
include AY, BY, and △Y, and they are all expressed in percentage.   
This oscilloscope allows you to set the reference position for the ratio 
according to your needs. After adjusting Y Cursor to a desired position, 
press Set Reference to take the current cursor position as the 
reference. The current positions of Cursor A and Cursor B are 
respectively defined as "0%" and "100%". Meanwhile, two cursors (in 
blue) that cannot be moved are displayed on the screen as the ratio 
reference position (the ratio position at "0%" and "100%" are 
respectively marked by a solid line and a dotted line). Before you set 
manually, the oscilloscope adopts the default ratio reference position. 
 
6.  Set LA Type 
When "LA" is selected under Source, you need to set the LA display type. Press 
More and then press La Type continuously to select "HEX" or "BIN". 
 
7.  Measurement Example 
Measure the period of a sine wave by using the manual cursor measurement 
and auto measurement respectively. The measurement results are both 1 ms, as 
shown in Figure 6-3.
