Data Input Precautions
• inputs the same data twice.
• You can also input multiple entries of the same data using (;).
T
o input the data 110 ten times, for example, press 110
(;) 10 .
• You can perform the above key operations in any order, and not
necessarily that shown above.
• While inputting data or after inputting data is complete, you can use the
and keys to scroll through data you have input. If you input
multiple entries of the same data using (;) to specify the data
frequency (number of data items) as described above, scrolling through
data shows both the data item and a separate screen for the data
frequency (Freq).
• You can then edit the displayed data, if you want. Input the new value
and then press the key to replace the old value with the new one.
This also means that if you want to perform some other operation
(calculation, recall of statistical calculation results, etc.), you should
always press the key first to exit data display.
• Pressing the key instead of after changing a value on the
display registers the value you input as a new data item, and leaves the
old value as it is.
• You can delete a data value displayed using and by pressing
(CL). Deleting a data value causes all values following it to be
shifted up.
