Trigger Mode
The M300 provides 5 trigger modes including auto trigger, manual trigger, external
trigger, absolute time trigger and alarm trigger.
Auto Trigger
In auto trigger mode, the scan rate is determined by the specified interval. If the
time required for a complete scan of the scan list is greater than the specified interval,
the instrument will execute a continuous scan at the fastest possible rate (no error
message will be generated).
The range of the interval is from 0 ms to 99:59:59.999 hours (the time format is
Hour:Minute:Second.Millisecond) and the resolution is 1 ms.
If the number of scans is set to “Infinite”, press Run/Stop at the front panel and the
instrument executes a continuous scan automatically at the specified interval. You
can press and hold the key to stop the scan.
If the number of scans is a specific value (1 to 50000), press Run/Stop at the front
panel and the instrument executes the specified number of scans at the specified
interval and then stops automatically.
During the scan, the instrument stores the measurement data, scaling data and
alarm data in the non-volatile memory automatically. You can press
at the front
panel to view the history measurement data (including the maximum, minimum,
average and standard deviation).
Manual Trigger
In manual trigger mode, after you press Run/Stop at the front panel, the
instrument executes a scan and then enters the wait-for-trigger state. After that, the
instrument triggers each time you press Run/Stop at the front panel.
If the number of scans is set to “Infinite”, after each trigger is finished, the
instrument will always stay in wait-for-trigger state. You can press and hold the key
to stop the scan and the instrument will exit the wait-for-trigger state.
If the number of scans is set to a specific value (1 to 50000), after the trigger is
finished, the instrument enters the wait-for-trigger state. The instrument will exit the
wait-for-trigger state when the number of triggers reaches the preset value.
During the scan, the instrument stores the measurement data, scaling data and
