The control output signal is 0V/5V (Low/High).
It is Low when integration measurement is being performed, and High when not
being performed.
NOTE
• The mark is displayed when integration is being performed through the
external control signal.
• Start/end of integration through the external control signal takes priority over
manual or time-and-date settings.
• The external control signal is valid even during integration standby or when
the setup screen is displayed. However, it is invalid while integration mea-
surement is being performed.
