Inputting Numerical Values
146
Numeral Setting
Input numerical values using the following numeric keys (touch switches): numer-
als (0 to 9, A to F), decimal point (.), sign (+,--), clear (CLR), and return (
S Changing the sign
S Confirming input numerical values
S Initial operation of input keys
S Upper/lower limit check
When there is a sign display, pressing the sign () key changes minus to plus or
plus to minus.
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 notified to the host.
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 ()
- Decimal point key (.)
- Alphabet (A to F) key
When using an NT-20S-ST121-EV3/ST122-V1 with Ver.5 direct connection,
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 valid range,
the data in the numeral memory table before input is redisplayed and not notified
to the host.
When inputting a numerical value that includes a decimal point, input the inte-
ger and decimal fraction separately. First input the integer, then press the deci-
mal point key (.) and input the decimal fraction.
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 dec-
imal point key (.) is not included. Therefore, it is necessary to create the deci-
mal point key (.) apart from the ten keys of the system keys to input a numerical
value including decimal fraction.
The display is cleared to zero (assuming decimal input with sign display).
The display is cleared to zero, after which input starts from the decimal fraction
digits (assuming decimal input with sign display).
The display is cleared to zero (assuming decimal input).
