External trigger Trigger on external input signal rising or falling edge (selectable).
Interval trigger The trigger is activated at a measurement interval set in days, hours,
minutes, and seconds.
Trigger criteria • AND or OR of each trigger source
• Trigger criteria can be set for each channel.
• Free-running when all are Off
Trigger types
Level Trigger Triggering occurs when the signal rises (or falls) through a specified
value.
Window Trigger Triggering occurs when the input signal level enters or exits the ampli-
tude window defined by upper/lower thresholds.
Pattern trigger Applies the trigger when a pattern defined in terms of 1, 0, and values
is matched (where " " indicates either value).
*Setting only available when using logic measurement with the LR8512.
Trigger response time Recording in 3 sec. or less

(with 1 unit, good communications)
Recording in 5 sec. or less

(When seven units are connected, good communications)
Trigger level resolution Analog: 0.1% f.s. (f.s. = 10 frames)
Pulse: Integration 1c, RPM 1/n (where n equals the pulse count setting
per revolution)
*Pulse setting only available when using the LR8512.
Rising : triggers upon transition from 0 V to 0.8 V (LOW)
to 2.5 V to 5.0 V (HIGH).
Falling : triggers upon transition from 2.5 V to 5.0 V
(HIGH) to 0 V to 0.8 V (LOW), or when the exter-
nal trigger terminal is shorted to a GND terminal.
