Using the external START/STOP terminals, recording start/stop can be
controlled for all functions.
START terminal Measurement starts when a signal is input here.
STOP terminal Measurement and printing stop when a signal is input
here.
Signal input method
・Short the terminal to ground, or input a pulse signal (High level: 2.5 to 5.0 V,
Low level: 0 to 1.0 V) or a square wave signal.
・Control is activated at the falling edge of the input waveform (active Low).
Voltage range High level: 2.5 to 5.0 V
Low level: 0 to 1.0 V
Pulse width High level: min. 20 ms
Low level: min. 30 ms
Maximum input voltage -5 to 10 V
