Remote integration start/stop control takes precedence over manual start/
stop and automatic start/stop at specified times. Remote control takes effect
even during the integration standby state and when a setting screen is
displayed. However, it is ineffective when integration has already begun and
is on.
• Monitoring time:
A start-to-stop period must be at least 30 seconds long. Do not change
the input signal within 30 seconds.
• Input levels
Low: 0.0 to 0.8 V
High: 2.0 to 5.0 V
• Allowable voltage:
The allowable voltage for the input terminals is –0.5 to 5.5 V.
9.6.2 Controlling Multiple CW120s and/or CW121s
When performing measurement with multiple CW120s and/or CW121s, you
can synchronously start and stop integration in all the CW120s and CW121s
by connecting external control terminals.
