8.2 Controlling Integration with External Signals

Chapter 8 Connecting External Devices
This control signal resets the integration value to zero.
It has the same effect as pressing the DATA RESET key on the instrument’s control panel.
This signal controls hold, manual save, or screen capture operation. It operates in the same manner as
the event set as the synchronization control function’s synchronization event.
See "7.5.1 Manually Saving Measurement Data" (p. 139) and "7.7 Saving Screen Capture Images" (p. 147).
Integration value reset (pin No. 1)
• This signal is ignored if it is input while integration is ongoing.
• Input this signal after allowing an interval of at least 250 ms (or when auto-saving is
on, at least 1 s) to elapse after integration stops.
5 V (open)
0 V (short)
40 ms or greater
The value is reset during this interval.
Event (pin No. 4)
• This signal is ignored if it is input while integration is ongoing.
• Input this signal after allowing an interval of at least 250 ms (or when auto-saving is
on, at least 1 s) to elapse after integration stops.
• To avoid damaging the instrument, do not input a voltage of 5.5 V or greater.
• Input chatter-free signals as control signals.
5 V (open)
0 V (short)
40 ms or greater
The value is reset during this interval.
