Numeral Setting
Section 4-8
If the integer or decimal fraction exceed their respective allowable numbers
of display digits, they are shifted to the left. In the system keys, however,
the decimal point key (.) is not included. Therefore, it is necessary to create
the decimal point key (.) apart from the ten keys of the system keys to input
a numerical value including decimal fraction.
• Changing the Sign
When there is a sign display, pressing the sign (
±
) key changes minus to
plus or plus to minus.
• Confirming Input Numerical Values
Always press the return key as the final step when inputting a numerical
value. When the return key is pressed, the displayed numerical value is
written to the numeral memory table and at the same time the host is noti-
fied.
• Initial Operation of Input Keys
The sign key (
±
), decimal point key (.), and alphabet key (A to F), operate
as follows on initial use (first use after displaying the screen).
• Sign Key (
±
)
The display is cleared to zero (assuming decimal input with sign dis-
play).
• Decimal Point Key (.)
The display is cleared to zero, after which input starts from the decimal
fraction digits (assuming decimal input with sign display).
• Alphabet Keys (A to F)
The display is cleared to zero (assuming decimal input).
• Upper/Lower Limit Check
When the return key is pressed after inputting a numerical value, an upper/
lower limit check is executed. If the input numerical value is outside the val-
id range, the data in the numeral memory table before input is redisplayed
and the host is not notified.
4-8-5
Using The Thumbwheel Type of Numeral Setting
When using the thumbwheel type of numeral setting, numerical values are
input by directly touching the incrementing/decrementing (+/–) keys.
Numerical Value Input
Input numerical values by using the incrementing/decrementing (+, –) keys
provided for each digit.
