Hioki LR8431-20 - About Recording Operation Modes

4.1 Setting Criteria to Start and Stop Recording
70
An input signal level “window” within which recording
will (or will not) occur can be defined by upper and
lower thre
shold levels. You can select whether record-
ing starts or stops when the input signal level enters
(In)
or exit
s (Out) of this window.
Upper and lower thresholds can be verified in the level
monito
r
or on the Waveform screen. When scaling is
enabled, the scaled threshold values are displayed.

1 Select [Window] as the [Cond] setting option
for the start or stop trigger.
2 Select inside [In] or outside [Out].
Setting options: ( default setting)
3 Enter the upper threshold value for the
[Upper] setting.
4 Enter the lower threshold value for the
[Lower] setting.
In Trigger when the input signal level enters the
window defined by the upper/lower thresholds.
Out Trigger when the input signal level exits the
window defined
by the upper/lower thresholds.
