x-data y-data , pressing will input the same data twice.

• Use

 

 

for same data multiple entries.

 

For

example in SD mode, the data 20 has 8 times will

press 20

 

8

 

 

 

.

 

 

 

 

 

• Press or

key during or after data input can display

the data value (x) and data frequency (Freq). Follow with the above example, press will display [x1 = 20], and press will display [Freq1= 8].

• To edit the stored data, input the new value during the display of that data value (x) after pressing or key,

and then press to confirm the edit. But, if you

press instead of , a new data value will be stored.
