Data collection timing by external one-shot trigger
(when enabled with falling edge)
The M-IN-START setting (T2) is ignored when this mode is selected.
But T1 stays enabled. Integration time depends on TX.
Data collection timing by external continuous trigger input
(when enabled with falling edge)
* Internal signal
+5 V
When EXT. TRIG is input while GATE is at High level,
data is enabled from the next scan.
