Data Sorting after Pretrigger Recording
The LED of the STOP key flashes while sorting pretrigger. Next recording will not be accepted
after completing this sorting process and the LED turns on. It may take a longer time on the
recording condition. Never cut the power while this sorting process, the power back up system
for data saving is not available for this moment.
Level Trigger Mode Setting
Condition of Level Trigger Activation
Recording by the level trigger does not start when the input signal already exceeds the up or
down cross of the preset trigger threshold level. Recording by the level trigger will start when an
input signal first crosses the point that passed set value under the following condition.
When the system detects that the signal goes over the pre-set threshold level 4 sampling times in
succession, the system observes the 5 th sampling data. If the signal exceeds the threshold level
at the 5
th
sampling, the system activates the trigger.
(This helps to prevent momentary noises from accidentally triggering the system.)
Presence of the trigger is recorded to AD data of CH1, LSB 1 bit.
