Displaying a Physical Constant and Its Information
1. h > Database
2. Highlight [Fundamental Physical Constants] and then press O or
r.
• This displays a list of Physical Constants categories.
3. Highlight the physical constant category whose values you want to
display and then press O or r. For example, to display the value
of Bohr magneton (μ
O or r.
• This displays a list of Electromagnetic category physical
constants and their values.
• See "Categorized List of Physical Constants" (page 185)
included in which category.
• See "Using a Physical Constant in a Calculation" (page 187)
physical constant values for calculations.
4. To display information about Bohr magneton, highlight the [μ
and then press O or select T > [Description].
• This displays a dialog with the applicable information (name,
symbol, units). To close the dialog, press O or b.
5. To return to the category list, press b.
Editing a Physical Constant Value
To edit a physical constant value
1. Perform the first three steps of the procedure under
(page 186) to highlight the physical constant whose value you want to edit.
2. Select T > [Edit] or press r.
• This displays the input cursor to the left of the value of the physical constant.
3. Use l and r to move the cursor to the digit you want to edit and then edit it as required.
• Only up to 15 significant digits are stored, even if you input more than 15 digits.
• An error (Syntax ERROR) occurs if you attempt to edit a constant using incorrect input.
