■ Numerical settings (confirming)
This operation is the same as the numerical value settings (immediate) described above, but the changes
do not become effective until the
ENTER
key is pressed.
A range check is performed when the
ENTER
key is pressed, and if a value that lies outside the set range
has been entered, an error message is displayed and the setting is returned to the value prior to the change.
If the
CANCEL
key is pressed, the change operations that have been performed up to that time (up and
down keys or knob) are canceled and the parameter values are returned to the original values.
■ Numerical settings (new input)
If any of the number keys
0
to
9
of the ENTRY keypad on the front panel are pressed or if the function
key [DIRECT NEW] at the bottom of the LCD screen is tapped while the menu is selected, the numerical
value input dialog
【
NUM

is displayed on the LCD screen. Numerical values that have been input with the
front panel ENTRY keypad and
【
NUM
】
dialog are set by pressing the
ENTER
key or tapping the
[ENTER] button.
Use the left and right keys to move the cursor position when editing numerical values. The digit to the left
of the cursor can be deleted by pressing the
BS
key or tapping on the
[BS]
button (backspace operation).

button) stands for the exponent (power of 10) and "e" is displayed in the value

key (or tapping the

button) discards what has been input and returns
to the value prior to input.
The function keys are used mainly for entering SI prefixes. It is also possible to add SI prefixes such as
"m" and "k" by tapping the function key after entering the numerical value with the numeric keypad.
