Controls starting/stopping of measurement by the 8730-10, 8731-10.
The START terminal (terminal No.: A6) corresponds to the
START
key.
The STOP terminal (terminal No.: A5) corresponds to the
STOP
key.
Controls the falling of a signal (active LOW).
The maximum delay from the falling edge until detection is 50 ms.
The START terminal does not accept signals when the BUSY terminal is
LOW.
When setting STOP terminal to LOW signal twice, the measurement will
be aborted.
Input Signal
The START terminal (A6) and STOP terminal (A5) must be shorted with
EXT_COM (A3), or a low-level signal must be input to these terminals.
