7.3 Trigger Settings – triG
The trigger setting determines which multimeter measurement values will be stored to the
adapter. Beyond this, storage to memory can be started by means of various trigger types
(st-ou, st-in, out, in). A trigger event occurs when high level is exceeded, or if low level is
fallen short of. Recording may take place before or after the trigger event.
Recording duration depends upon the sampling rate, the hysteresis setting, available mem-
ory capacity and the desired recording duration (durA).
The recording command (after all settings are complete) is executed with the hot-key combi-
nation ESC and
, or in the StorE menu.
• Start Recording as of the Trigger Event (without re-trigger or pre-trigger)
a) The prescribed trigger activation time is reached. The trigger is active as of this point in
time.
b) A trigger event occurs. Recording is started and runs for the selected duration (durA).
c) The recording duration (durA) has transpired and recording is stopped – it may also be
stopper earlier if insufficient memory capacity is available, or if the cyclical memory mode
(CYLCE) has been selected.
• Multiple Recordings as of the Trigger Event (with re-trigger)
Only possible for trigger types triG = in and triG = out.
The pre-trigger must be disabled for this recording mode (PrEtr = oFF)!
a) b), c) Same as above example without re-trigger or pre-trigger.
d) The trigger is once again active as soon as recording has ended.
• Recording Before the Trigger Event, or Immediate Recording (with pre-trigger)
a) The prescribed trigger activation time is reached. The trigger is active as of this point in
time. Recording begins (da PrEtr = on). A recording duration (durA) can be selected in
this case as well, in order to stop recording.
b) A trigger event occurs and recording is stopped.
