u To specify the number of significant digits ( Sci)
Example To specify three significant digits
2(Sci) dw
Press the number key that corresponds to the number of significant digits you want to specify
(
n = 0 to 9). Specifying 0 makes the number of significant digits 10.
• Displayed values are rounded off to the number of significant digits you specify.
u To specify the normal display ( Norm 1/Norm 2)
Press 3(Norm) to switch between Norm 1 and Norm 2.
Norm 1: 10
