Question
Is it possible to display only '+' and '-'?
Answer
Yes, it is possible.
Models with binary-coded decimal (06 models) are available that display
"+, -, +, -. . ." rather than "0, 1, 2, 3, 4, 5 . . . 9".
The models are the A7[]-206-PM and A7[]-206-PM-1.
Example:
A7BS-206-PM Thumbwheel Switch
Output Code:
The signal between output terminal 1 and the COM terminal of the
Thumbwheel Switch is used as the binary code.
