Entering the Numeral Values
The numeral values are entered using the ten-key numeric (0 to 9, A to F), deci-
mal point (.), sign (+/–), clear (CLR), RETURN (
) keys.
The numeral values can be entered in the same manner as a general electric
calculator as follows:
•
Entering the integer part and decimal fraction
An integer part is entered from the least significant digit. When an input numer-
al value is in excess of display digits, the numeral value shifts to the left from the
least significant digit.
When a decimal point is entered, a decimal fraction can be entered thereafter.
The decimal fraction is entered from the most significant digit. When an input
numeral value is in excess of display digits, the numeral value shifts to the right
from the most significant digit.

•
Changing the sign
In case of sign display setting, the sign alternates from “+” to “–” and vice versa,
each time the sign (+/–) key is pressed.
•
Confirming the input numeral value
Be sure to press the RETURN key after an input operation is completed. When
the RETURN key is pressed, the numeral value displayed is written into the
numeral memory table and simultaneously notified to the PC.
•
Initial operation of the input keys
When the sign (+/–), and decimal point(.) keys are pressed initially (when
pressing these keys immediately after displaying a screen or inputting the
keys), the NT610C will operate as follows:
- Sign (+/–) key
The display is cleared by “0”, but the sign is not reversed (when entering a
decimal number or displaying a sign).
- Decimal point (.) key
The display is cleared by “0”. The NT620S/620C starts entering the decimal
fraction (when entering a decimal number or displaying a decimal fraction).
•
Checking the upper/lower limits
The upper/lower limits are checked when pressing the RETURN key after an
input operation is completed. If it is found that an input numeral value is in ex-
cess of limit as a result of checking, the contents of the numeral memory table
(previous values prior to entry) is displayed again, but this is not notified to the
PC.

Example of input
Numeral display varies as shown below when actually entering numeral val-
ues.
