(3) When conditions are manually switched in internal trigger mode and local mode
The following diagram shows the lapse of time in the case where measurement by
laser processing is performed 3 times after the measurement condition number is
manually switched, all 3 times are judged as OK, and pulse output is made.

*3: The internal trigger is applied when the measured value obtained by emitted light
from the processing end exceeds the trigger value set in the
MM-L300A
.
Therefore, it varies depending on the laser condition and the workpiece material,
or set trigger value, etc.
Also, the timing cannot be matched to the laser output start due to the
specification above.
To match it, switch the mode to the external trigger mode and input the external
trigger to the
MM-L300A
at the same timing as the laser oscillation signal.
*4: The minimum time from measurement end to start of the
MM-L300A
is 1
μ
s.
However, at least 500
μ
s is required for check a correct measurement judgment
output. (Refer to 8. (2) Conditions for Obtaining Waveform .)
Specify the time from the laser end to the next laser output start considering
above.
