Hioki LR8402-20 - Setting Trigger Criteria

5.1 Triggering Measurement Start and Stop
102
Using Level Triggering
Enter the signal level threshold at which to start or stop measuring,
and whether triggering occurs on the upslope or downslope of the
input signal.
Recording starts or stops when the signal crosses the specified
threshold. The level value is an instantaneous (not rms) value.
Levels can be confirmed on the level monitor or on the Waveform/Numerical screen.
Make trigger settings on the [CH] screen of the displayed channel.

1 Select [Level] as the start/stop trigger type.
2 Select the input signal rising () or falling ()
edge setting option.
3 Set the input signal level at which to start or stop
measuring.
Setting options: (  : default setting)

Measurement starts (or stops) when the signal cross-
es the threshold on the upslope (rising edge
).

Measurement starts (or stops) when the signal
crosses the threshold on the downslope (falling
edge
).
