Inputting Numerical Values
Input numerical values using the following numeric keys (touch switches): numer-
als (0 to 9), decimal point (.), sign (+,--), clear (CLR), and return (
).
Inputting the integer and decimal fraction parts
When inputting a numeric valueincluding a decimal point, input the integerand
decimal fraction separately. First input the integer, then press the decimal
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.
Note that the system keys do not have a decimal point (.) key. Accordingly, it is
necessary to make a decimal point key in addition to the system keys to input
numeric values including a decimal point.
Changing the sign
When there is a sign display, pressing the sign ( ) key changes minus to plusor
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 notified to the host.
Initial operation of input keys
The return key (
), sign key ( ), decimal point key (.), operate as follows on
initial use (first use after displaying the screen or first use after key input).
- Return key (
)
The display is cleared to zero (assuming decimal input width sign display).
-Signkey( )
The display is cleared to zero (assuming decimal input with sign display).
- 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 (A to F) key
The display is cleared to zero (assuming decimal input).
